Knowledge of specific plant characteristics in a germplasm collection and of the relationships between characteristics facilitates efficient use of that collection. The objectives of this study were to develop an information system for a collection of flax (Linum usitatissimum L.), including inventory control, morphologic, agronomic, and quality characteristics, and to utilize programs to analyze relationships between these characteristics. The search for a single character or any combination of a number of characters can be accomplished, ranked in order or by accession number and name. Genetic relationships between characteristics can also be determined. Efficient management of a germplasm collection is feasible for a curator located at an outlying university or research center, and is time and labor saving. The system developed permits rapid response to user’s queries in sending information regarding specific characteristics as well as seed to any improvement program.

AbstractApplication of high rates of [(4‐chloro‐o‐tolyl)oxy] acetic acid (MCPA) on four relatively homogeneous populations of flax (Linum usitatissimum L.) for seven successive generations and on two heterogeneous populations for three successive generations (F2, F2, and F4) caused no detectable genetic change in yield, oil content, iodine value, or maturity. Tolerance to MCPA was not increased by successive generation treatment with MCPA.The lack of detectable mutants in the progenies of flax populations sprayed with high rates of MCPA for several successive generations suggested that MCPA was not mutagenic. The frequency of mutations should not be increased as a result of successive applications of MCPA to commercially grown flax cultivars or to breeding populations.

The selective pathogenicity of races of Melampsora lini (Ehrenb.) Lev. was utilized to identify rust‐conditioning genes in cultivars of flax (Linum usitatissimum L.). New rust‐resistant cultivars developed for commercial production possessed the rust‐conditioning genes expected based on knowledge of their parents. A heretofore‐unknown gene, designated L11, was identified in ‘Linore,’ a cultivar of unknown parentage. This gene conditions resistance to all North American races of rust. Tests of several hundred cultivars of foreign origin revealed that most introductions are heterogenious for rust reaction.

Seed yield, its three components (bolls per unit area, seed size, and seeds per boll), oil content, and iodine value were studied in F2 populations of a diallel cross among nine cultivars of flax (Linum usitatissimum L.) at two locations and three plant densities.Average heterosis for yield in F2 was 6% relative to the midparent values. Four F2 populations exceeded in yield the high‐yielding parent by 15 to 19%. One F2 population, ‘Russian’ ✕ C.I. 1664, exceeded by 5.5% the yield of ‘Marine’, the highest yielding cultivar. Varying plant density did not affect the magnitude of heterosis, mean oil percentage, iodine value, nor the estimates of combining ability. Plant density did have a significant effect on mean yields and on the yield components, and showed a significant interaction with genotypes for yield and bolls per unit area. In spite of the latter interaction, seven of the 36 F2 populations were among the highest 25% in yield in all three densities. The interactions of locations with genotypes were significant for most characters, which suggests that more than one test location should be used to evaluate hybrid flax populations. General combining ability effects were significant and much larger for all characters than were specific combining ability effects at all densities.

Lines of seed.flax (Linum usitatissimum L.), each with a different gene for rust resistance, were developed by backcrossing to the cultivar ‘Bison.’ The monogenic Bison‐like lines were intercrossed to provide two‐gene segregates. Intercrossing two‐gene lines, with one gene in comtnon, develnped three‐gene lines. The selective pathogenicity of races of Melampsora lini (Ehrenb.) Lev., was utilized to identify plants that possessed the parental resistance genes. In a 3‐year trim (1966–1968) at Fargo, North Dakota, yield differences between 20 multiplegene cultivars and five commercial cultivars were not significant. Most of the experimntal cultivars would be satisfactory for commercial production.

Comparison of agronomic and seed quality characters of 17 near‐isogenic pairs of flax lines showed that the d locus was not associated with seed yield, maturity, height, or seed germination. Lines homozygous for the recessive d allele (yellow seed and pink flowers) had significantly smaller seed and higher iodine value than lines homozygous for the dominant D allele (brown seed and blue flowers). Percent oil of the two seed color classes differed significantly in each of four trials, but the differences were not consistent. High oil content was associated with the recessive allele in half the trials, but with the dominant allele in the other 2 trials. The analyses of variance strongly suggests that the chromosomal segment adjacent to the d locus is active in determining oil content and seed size, and that the d locus has a pleiotropic effect upon iodine value.

Progeny arising from crosses between 2‐methyl‐4‐chlorophenoxyacetic acid (MCPA)‐tolerant and MCPA‐susceptible flax varieties were evaluated for MCPA tolerance in F3, F4, BC(S2), and BC(S3) generations. Data were obtained on the change in anthocyanin production and stem curvature, delays to first bloom, full bloom, and maturity, and on the reduction of plant height andseed yield.Based on heritability estimates, selection would be most effective for change in anthocyanin production, stem curvature, and reduction in plant height in the ‘Arrow’ ✕ ‘Dakota’ cross and most effective for stem curvature, and delays to first bloom and to maturity in the Arrow ✕ C.I. 1139 cross.
