Water status measurements of excised leaves have been proposed as screening criteria for drought resistance in cereal crops. This study was conducted to assess the utility of such measurements in a wheat breeding program, through evaluation of environment and genotype differences in excised-leaf water status and examination of associations with several other traits. Initial water content (IWC) and rate of water loss (RWL) of excised leaves, epicuticular wax content (EW), stomatal frequency (SF), flag leaf area (LA), plant height (HT), heading date (HD), grain yield (GY), and test weight (TW) were measured on 24 winter wheat (Triticum aestivum L.) genotypes grown near Fort Collins, CO, during 1986-1987 and 1987-1988 (F87 and F88, respectively: subirrigated environments) and near Bennett, CO, during 1987-1988 (B88: dryland environment). Differences among genotypes for IWC and RWL were significant for F87 and F88, and nonsignificant for B88. Combined analyses of variance showed significant differences among environments for IWC and RWL. Initial water content was less for B88 than for F87 and F88. Significant genotype x environment (G x E) effects for IWC and RWL suggested that selection for high IWC or low RWL in irrigated environments (F87 and F88) may not provide selections that respond similarly in dryland environments (B88). Correlations for B88 revealed only a small, positive correlation between IWC and GY (r = 0.49*). For F87 and F88, significant correlations were observed between IWC and SF (r = -0.57** and -0.78**), RWL and LA (r = 0.74** and 0.71 **), RWL and HT (r = 0.63** and 0.57**), and RWL and HD (r = 0.71** and 0.57**). Neither IWC or RWL were correlated with EW in any environment. Correlations between RWL (subirrigated) and GY and TW (dryland) suggested that selection for low RWL in irrigated environments could provide some GY or TW advantage in dryland environments, despite observed G x E interaction and lack of RWL differences under the dryland environment.

The PI 386148 triticale from Russia is among the highest resistant line to the Russian wheat aphid (RWA) (Diuraphis noxia (Mordvilko)). This triticale line was used as the male parent in crosses with Lamar wheat (Triticum aestivum L.). The F-1 plants were backcrossed to Lamar wheat. The progenies were tested for RWA biotype 1 reaction for at least eight backcross and selfing generations. Five lines from these selections were identified for their resistance to the RWA and their seeds were increased for agronomic and other characterizations. Molecular and cytological analyses of these lines were performed using genomic in situ hybridization and rye chromosome-specific microsatellites markers. Three lines were cytologically stable and carried a pair of rye (Secale strictum (C. Presl) C. Presl) chromosomes as disomic addition lines of 1R. One line was unstable and showed a moderate level of mixoploidy with monosomic additions of 1R. Duplication of rye chromosome 1R was also identified. No wheat-rye chromosome interchange was detected, suggesting little homology between S. strictum and T. aestivum chromosomes. Specific microsatellite primers were used to identify the rye chromosomes present in each line. One rye chromosome, 1R, from the donor species contains genes for RWA resistance. Grain yield and test weight of three of the lines were similar to some adapted released wheat varieties under stress conditions.

Durum wheat (Triticum turgidum L. var. durum) is traditionally used for the production of numerous types of pasta, and significant amounts are also used for bread-making, particularly in southern Italy. The research reported here centres on the glutenin subunits 1Dx5 and 1Dy10 encoded by chromosome 1D, and whose presence in hexaploid wheats is positively correlated with higher dough strength. In order to study the effects of stable expression of the 1Dx5 and 1Dy10 glutenin subunits in different durum wheat genotypes, four cultivars commonly grown in the Mediterranean area (‘Svevo’, ‘Creso’, ‘Varano’ and ‘Latino’) were co-transformed, via particle bombardment of cultured immature embryos, with the two wheat genes Glu-D1-1d and Glu-D1-2b encoding the glutenin subunits, and a third plasmid containing the bar gene as a selectable marker. Protein gel analyses of T1 generation seed extracts showed expression of one or both glutenin genes in four different transformed durum wheat plants. One of these transgenic lines, DC2-65, showed co-suppression of all HMW-GS, including the endogenous ones. Transgene stability in the transgenic lines has been studied over four generations (T1–T4). Fluorescence in situ hybridization (FISH) analysis of metaphase chromosomes from T4 plants showed that the integration of transgenes occurred in both telomeric and centromeric regions. The three plasmids were found inserted at a single locus in two lines and in two loci on the same chromosome arm in one line. The fourth line had two transgenic loci on different chromosomes: one with both glutenin plasmids and a different one containing only the construct with the gene encoding the 1Dy10 glutenin subunit. Segregation of these two loci in subsequent generations allowed establishment of two sublines, one containing both 1Dx5 and 1Dy10 and the other containing only 1Dy10. Small-scale quality tests showed that accumulation of Dx5, Dy10 or both in transgenic durum wheat seeds resulted in doughs with stronger mixing characteristics.

A field experiment was conducted to determine whether resistance to Russian wheat aphid, Diuraphis noxia (Mordvilko), conferred by the Dn4 gene is affected by genetic background. This was done by comparing the yield responses to Russian wheat aphid-resistant wheat containing Dn4, derived through the backcross method, to those of the corresponding recurrent parents. Infested resistant cultivars had fewer Russian wheat aphids per tiller than infested susceptible cultivars at the Lamar and Fort Collins, CO sites but not at the Akron, CO site. At the Lamar site, resistant cultivars yielded more than the susceptible cultivars. 'Prairie Red' and 'Yumar' were more resistant than 'Prowers', especially at the higher infestation level. Resistance in these cultivars was categorized in a laboratory experiment to confirm this differential expression of resistance. Resistance in Prairie Red, 'Halt', 'Prowers 99', and Yumar was categorized at three plant growth stages. Antibiosis was expressed as reductions in maximum number of nymphs produced per 24 h and intrinsic rate of increase. The maximum number of nymphs produced per 24 h was reduced in Halt and 'Lamar'. Averaged over cultivars, the intrinsic rate of increase was less at jointing than at the seedling or tillering growth stages. Tolerance was expressed in the resistant cultivars as reduced chlorosis and leaf rolling. Growth reductions in infested Prowers 99 plants was less than the other cultivars. This study confirms that some cultivars containing Dn4 may express antibiosis and tolerance, whereas others may not show the same categories. Thus, expression is affected by genetic background.

'Hatcher' (Reg. no. CV-971, PI 638512) hard red winter wheat (Triticum aestivum L.) was developed by the Colorado Agricultural Experiment Station and released to seed producers in August 2004. Hatcher was released based on its resistance to the original North American biotype, designated as Biotype 1 (D.R. Porter, personal communication, 2004) of the Russian wheat aphid [Diuraphis noxia (Mordvilko)], and its adaptation to nonirrigated production in eastern Colorado and the west-central Great Plains. 'Hatcher' was named in honor of the late E.L. "Shug" Hatcher, a former Colorado Wheat Industry leader who farmed near Lamar, CO. Hatcher was selected from a population derived from a series of crosses and backcrosses completed in 1993: 'Yuma'/PI 372129//'TAM-200'/3/4*Yuma/4/KS91H184/'Vista'. PI 372129 is a Russian wheat aphid–resistant landrace from Turkmenistan that carries the Dn4 Russian wheat aphid resistance gene (Quick et al., 1991); Yuma (PI 559720) is a hard red winter wheat cultivar released by Colorado State University in 1991; TAM-200 (PI 578255) is a hard red winter wheat cultivar released by Texas A&M University in 1986 (Worrall et al., 1995); Vista (PI 562653) is a hard red winter wheat cultivar released by the University of Nebraska in 1992 (Baenziger et al., 1993); and KS91H184 is an experimental line from Kansas State University (T.J. Martin, personal communication, 2004) derived from a random mating population involving CI 17884 (Wells et al., 1982). Following each backcross with Yuma as recurrent parent, progeny were screened for Russian wheat aphid Biotype 1 resistance in standard greenhouse screening tests (Nkongolo et al., 1989), and resistant plants were used as parents for the next cross. The final cross was made between a Russian wheat aphid-resistant BC3F1 plant and an F1 plant from the cross KS91H184/Vista. Based on visual uniformity and agronomic appearance, Hatcher was selected in 1998 as an F4:5 line following advance from the F2 through the F4 using the bulk breeding procedure. Hatcher was assigned experimental number CO980607 and evaluated in nonreplicated preliminary yield trials in 1999, replicated advanced yield trials in 2000, replicated statewide variety trials from 2001 to 2004, and the Southern Regional Performance Nursery (SRPN) in 2003 and 2004. Seed purification of Hatcher was done by visual identification and removal of off-type rows among 135 F9:11 headrows grown at Yuma, AZ, in 2002 and bulking the seed from rows with uniform appearance. Breeder seed (F9:12) was produced in 2003 under irrigation in Colorado. Hatcher is an awned, white-chaffed, medium maturity, semidwarf hard red winter wheat. Hatcher has medium maturity, 144 d to heading from 1 January, and is 4 d later than 'Prairie Red' (PI 605390) and 1 d later than 'Yumar' (PI 605388) and 'Ankor' (PI 632275). Plant height of Hatcher is short (65.5 cm), and is 1.5 cm shorter than Prairie Red and 4.1 cm shorter than Yumar and Ankor. Coleoptile length of Hatcher (73.6 mm, n = 8 observations) is shorter than that of Prairie Red (85.0 mm) and Ankor (77.4 mm) but longer than that of Yumar (62.9 mm). Shattering tolerance of Hatcher is good (3.6 score, 1 = no shatter to 9 = severe shatter, n = 3 observations), slightly less than Ankor (2.7 score) but better than Prairie Red (4.1 score) and Yumar (4.2 score). On the basis of evaluations through the USDA Regional Testing Program, Hatcher is moderately susceptible to stem rust (caused by Puccinia graminis Pers.:Pers f. sp. tritici Eriks. & E. Henn; composite of races QFCS, QTHJ, RCRS, TPMK, and TTTT) and leaf rust (caused by Puccinia triticina Eriks.; composite of races MLRT, MFBP, TKBP, TDGT, and KBQT). The rating scale of infection responses in these evaluations consisted of four classes: R (resistant), MR (moderately resistant), MS (moderately susceptible), and S (susceptible) determined primarily on the basis of the size of uredinia. Based on natural field infection in Colorado, Hatcher is moderately resistant to stripe rust (caused by Puccinia striiformis Westend.; 4.3 score, 1 = resistant and 9 = susceptible, n = 4 evaluations). Based on cooperative evaluations through the USDA Regional Testing Program, Hatcher is susceptible to both Wheat streak mosaic virus and Barley yellow dwarf virus, heterogeneous for resistance to the Great Plains biotype of Hessian fly [Mayetiola destructor (Say)], and susceptible to greenbug [Schizaphis graminum (Rondani)]. Resistance to Russian wheat aphid Biotype 1 in Hatcher is conditioned by the Dn4 resistance gene. Russian wheat aphid resistance scores for Hatcher (1.9 score, 1 = very resistant to 5 = very susceptible, n = 12 observations) in standard greenhouse seedling screening tests using Biotype 1 are similar to other cultivars that carry Dn4 including Yumar (2.2 score), Prairie Red (2.2 score), and Ankor (1.9 score). Hatcher was tested at 22 trial locations of the Colorado Dryland Uniform Variety Performance Trial (UVPT) during 2001 (eight locations), 2002 (three locations), 2003 (six locations), and 2004 (five locations). Mean grain yields of Hatcher (3118 kg ha−1) were slightly lower than that of 'Trego' (3178 kg ha−1; PI 612576) but higher than those of all other entries tested including Ankor (3011 kg ha−1), Prairie Red (2964 kg ha−1), and Yumar (2943 kg ha−1). Average grain volume weight of Hatcher (748 g L−1) was lower than that of Trego (768 g L−1) but similar to that of Yumar (746 g L−1) and higher than that of Ankor (740 g L−1) and Prairie Red (739 g L−1). Hatcher was tested at eight locations of the Colorado Irrigated Variety Performance Trial (IVPT) during 2002, 2003, and 2004. In these trials, Hatcher (6598 kg ha−1) had a lower mean yield than Prairie Red (7015 kg ha−1) but a higher mean yield than Ankor (6510 kg ha−1). Average grain volume weight of Hatcher (745 g L−1) was higher than that of both Prairie Red and Ankor (723 g L−1). The straw strength of Hatcher in these irrigated trials was moderate (4.6 score, 1 = erect to 9 = flat scale, n = 9 observations), and weaker than those of Ankor (3.9 score) and Prairie Red (2.3 score). Hatcher was tested in the 2003 and 2004 Southern Regional Performance Nursery (SRPN). Across locations in the High Plains region, Hatcher was the second highest entry in the trial in both 2003 (seven location mean yield 4697 kg ha−1; 46 total entries) and 2004 (nine location mean yield 3533 kg ha−1; 50 total entries). Milling and bread baking characteristics of Hatcher were determined from multilocation composite grain samples in 2000, 2001, and 2002 and three single-location evaluations in 2001 (n = 6 observations). Ankor and 'Prowers 99' (PI 612420) were used as checks in these evaluations. Values for milling-related variables were generally superior to both Ankor and Prowers 99. Hatcher had higher grain volume weight (761.9 kg m−3) than Ankor (732.3 kg m−3) and Prowers 99 (749.0 kg m−3). On the basis of Single Kernel Characterization System (SKCS) analysis, Hatcher had higher kernel weight (28.5 mg kernel−1) than Ankor (25.2 mg kernel−1) and Prowers 99 (26.3 mg kernel−1); higher SKCS kernel diameter (2.17 mm) than Ankor (2.03 mm) and Prowers 99 (2.11 mm); and lower SKCS kernel hardness index (71.8 score) than Ankor (73.3 score) and Prowers 99 (80.0 score). Hatcher had higher Quadromat Senior flour extraction (685 g kg−1) than Ankor (658 g kg−1) and Prowers 99 (679 g kg−1) and lower flour ash (4.1 g kg−1) than Ankor (4.4 g kg−1) and Prowers 99 (4.8 g kg−1). Values for baking-related variables of Hatcher were generally intermediate between Ankor and Prowers 99. Hatcher (120 g kg−1) had similar grain protein content as Ankor (120 g kg−1) and lower than Prowers 99 (138 g kg−1). In mixograph tests optimized for water absorption, Hatcher had higher water absorption (618 g kg−1) than Ankor (615 g kg−1) and lower than Prowers 99 (649 g kg−1); higher tolerance score (3.2 score; 0 = unacceptable to 6 = excellent scale) than Ankor (2.2 score) and lower than Prowers 99 (4.0 score); and longer mixing time (3.2 min) than Ankor (2.9 min) and shorter than Prowers 99 (4.0 min). In straight-grade pup loaf baking tests, Hatcher had lower bake water absorption (600 g kg−1) than Ankor (604 g kg−1) and Prowers 99 (633 g kg−1); longer bake mixing time (4.2 min) than Ankor (3.6 min) and shorter than Prowers 99 (5.1 min); smaller pup loaf volume (0.872 L) than Ankor (0.888 L) and Prowers 99 (0.945 L); and lower loaf crumb grain score (3.8 score; 0 = unacceptable to 6 = excellent scale) than Ankor (4.0 score) and Prowers 99 (4.5 score). The Colorado Agricultural Experiment Station will maintain Breeder seed of Hatcher. Multiplication and distribution rights of other classes of Certified seed have been transferred from the Colorado Agricultural Experiment Station to the Colorado Wheat Research Foundation, 7100 S. Clinton St. Suite 120, Centennial, CO 80112. Hatcher has been submitted for U.S. Plant Variety Protection under Public Law 91-577 with the certification only option.

A study to determine yield response to the Russian wheat aphid, Diuraphis noxia (Mordvilko), was conducted during the 1997-1998 and 1998-1999 growing seasons at three eastern Colorado locations, Akron, Fort Collins, and Lamar, with three wheat lines containing either Russian wheat aphid-resistant Dn4 gene, Dn6 gene, or resistance derived from PI 222668, and TAM 107 as the susceptible control. Russian wheat aphids per tiller were greater on TAM 107 than the resistant wheat lines at the 10X infestation level at Fort Collins and Akron in 1999. Yield, seed weight, and number of seeds per spike for each wheat line were somewhat affected by Russian wheat aphid per tiller mainly at Fort Collins. The infested resistant wheat lines harbored fewer Russian wheat aphids and yielded more than the infested susceptible wheat lines. Wheat lines containing the Dn4, Dn6, and PI 222668 genes contain different levels of antibiosis or antixenosis and tolerance. Although differences existed among sites and resistance, there is a benefit to planting resistant wheat when there is a potential for Russian wheat aphid infestations.

Plant damage and yield response to the Russian wheat aphid, Diuraphis noxia (Mordvilko), were evaluated on a susceptible (TAM 107) and a resistant (RWA E1) winter wheat, Triticum aestivum L., in three Colorado locations in the 1993 and 1994 crop years. Russian wheat aphid was more abundant on TAM 107 than on RWA E1. Russian wheat aphid days per tiller were greater at the higher infestation levels. Yield losses as a result of Russian wheat aphid infestation occurred most of the time with TAM 107 but rarely with RWA E1. Seed densities were reduced at higher infestation levels in TAM 107 at two locations. Russian wheat aphids per tiller had a negative relationship to yield in TAM 107 but not in RWA E1. In TAM 107 yield decreased as aphid densities increased, but yield remained constant regardless of initial aphid abundance on RWA E1 in all environments. Seed densities were reduced at higher infestation levels in TAM 107 at two locations. The resistance conferred by the Dn4 gene seems to be an effective management approach across a range of field conditions.

Sources of partial resistance to crown rot caused by Fusarium pseudograminearum are detected in mature plants grown in artificially inoculated soil in the field. The resistance in most but not all of these sources can also be detected in seedlings. In order to determine whether partial resistance is related to depth of crown formation, this character was measured in 13 cultivars/lines with a range of reaction to crown rot. It was also measured in doubled haploid plants from the cross, Batavia/2–49. Crown depths varied from 17.1 mm to -2.3 mm (above ground) in pots in a waterbath at 25 ° C and from 43.5 mm to 20.7 mm when plants were grown in the field. The correlation coefficient between relative susceptibility to crown rot (Field test) and crown depth of 13 cultivars/lines was 0.57 ( p ≤ 0.05). With the exception of the cultivars, Sunco and Pelsart, partial resistance to crown rot was inversely related to depth of crown formation. This indicates that depth of crown formation may be partly responsible for the reaction of a cultivar/line to crown rot. Depth of crown formation was also measured in susceptible and partially resistant cultivars/lines grown from seed planted at different depths. As depth of seeding increased, depth of crown formation in partially resistant and susceptible cultivars/lines increased in similar proportions.
