Objective Effects of seed sowing time and ambient temperature at grain-filling on the agronomic traits and rice quality/flavonoid content of Ziliangyou 737 were analyzed for improved the cultivation. Method Seeds of Ziliangyou 737 were sowed at intervals to vary the growing period and harvest season for studying the effects of sowing time and atmosphere temperature at grain-filling stage on the agronomic traits of the plants and quality and flavonoid content of the rice. In 7, 10, 14, and 21 d after start of grain-filling as well as at grain maturity, data were collected for a statistical analysis on the rice crops sowed on various dates. Result Under a shorter growing season, the plant height declined; the spike length became longer, then shorter; the seed setting rate and yield reduced, then increased; and the effective accumulated temperature (EAT) decreased gradually. The ∑H (High temperature hours) and ∑Th (Thermal accumulated temperature hour) within 10 d after grain-filling significantly affected the seeding rate of the mature seeds, so did the TA (Average temperature) within 14 d after grain-filling. When TA was 31.645 ℃, the seeding rate reached the lowest level, but the effect was lessened with increasing ambient temperature as the grain matured. High ∑Td (Daily thermal accumulated temperature) at 21 d after initial filling resulted in higher rate of failed grain-filling which translated to a lower seeding rate. VB5, VB6, and VB2 were the vitamins in the greatest amounts found in the grains, but no significant correlation was found between vitamin contents and sowing time. Late sowing caused linear decline in grain amylose due to decreased ∑H, ∑Td, and ∑Th. High temperature affected the amylose content positively, but the effect was less at the late filling stage. Controlling TA at a level below 26.84 ℃ could help maintain the quality of the waxy rice crop sowed in late season in Fujian. The contents of anthocyanins and flavonoids correlated to the sowing time as shown by the color of seed hull that changed from reddish brown to dark black. From 14 d after grain-filling till maturity, ∑Td, TA, and EAT became extremely significant factors in the color change as a rising temperature mitigated anthocyanins and flavonoids.ConclusionScheduling of Ziliangyou 737 sowing significantly affected the growth and grain quality of the waxy rice. By controlling a TA less than 26.84 ℃ and an EAT at 2336.69–2390℃·d during grain-filling, crop yield and rice quality could be maximized. In Fujian, sowing between June 15 and 25 would thus be desirable. For other localities, cultivation in areas at high altitude or those that provide low TA at grain-filling stage would be recommended for Ziliangyou 737.

Objective Functional components and yield-related traits of Ziliangyou 737 and its parents were determined. Method Functional components and yield-related agronomic traits of Ziliangyou 737 were compared with those of Zi 392S, Fuhui 737, the white rice control Yiyou 673, and the black rice control Mojiangzimi. Result Ziliangyou 737 was rich in antioxidants (e.g., anthocyanins) and functional ingredients (e.g., essential amino acids and minerals) carrying mostly additive genetic characteristics relating to antioxidant capacity and phenotypes of F1 generation biased towards low-value parents. A strong heterosis of the cross breeding was evident by the upgraded yield-related traits of Ziliangyou 737.ConclusionRich in antioxidants and functional components, the purple glutinous hybrid rice Ziliangyou 737 was also high on the traits related to crop yield. This study illustrated a promising direction for breeding specialty rice varieties.

ObjectiveThis study was conducted to analyze the genotypes of yield and quality-related traits of the purple waxy special rice Ziliangyou 737 and its parents, and to provide molecular basis for the further application of this variety and its parents in breeding and production.MethodUsing 13 molecular markers of 10 important genes, the alleles of Ziliangyou 737 and its parents Ziliang392s and Fuhui 737 were analyzed in relation to yield and quality.ResultIn 7 gene loci, both Zizliangyou 737 and its parents carry the same allele genotype. The high-yield allele Ha-Gn1a was carried in the seat of Gn1a, the major gene of panicles number. The long grain allele MH-GS3 was carried in the GS3 locus of the major gene for grain weight and grain length. The alleles of purple pericarp were carried in the Pb locus of seed coat gene. All alleles with low amylose content in waxy gene wx locus were carried in glutinous rice. In addition, the same allelic genotype was carried in the starch branch enzyme genes SBE1 and SBE3 and the limit dextrin enzyme gene PUL gene locus. In three loci, parents carry different alleles. In the Hd3a seat, the Zi 392S, Fuhui 737 and Ziliangyou 737 carry Hd3aNip, hd3aKasa and Hd3aNip/hd3aKasa respectively. On the Hd1 seat, carry Hd1jap, Hd1ind and Hd1jap/Hd1ind respectively. In the large subunit gene AGPlar locus of pyrophosphorylase, there were type I, type II and hybrid type I/II, respectively.ConclusionThe genetic analysis of important agronomic traits of Ziliangyou 737 provided molecular evidence for its high yield, high quality, good adaptability and seed coat color, and provided reference for further utilization of related favorable alleles
