四川近十年小麦主栽品种的品质状况
Quality of Major Wheat Cultivars Grown in Sichuan Province in Recent Dec-ade
摘要
Abstract
Quality improvement is one of the major targets in winter wheat breeding in Southwest China in the past two decades. This study aimed at understanding the quality of the main varieties released in Sichuan province, especially evaluating the quality and the breeding value of synthetic hexaploid wheat (SHW). In multi-environment trial from 2011 to 2013 (location × year), we evaluated the grain protein content (GPC), grain germination index (GI), falling number (FN), wet gluten content (WGC), sedi-mentation value (SDS), flour yield (FY), farinograph parameters, and Rapid Visco Analyzer (RVA) parameters of 10 wheat com-mercial cultivars. The results showed that genotype, environment, and genotype × environment interaction had significant effect on all quality parameters tested. The effect of environment was greater than that of genotype in most traits related to protein quan-tity and quality;whereas, the genotypic effect was greater than environmental effect in starch quality traits including FN and RVA parameters. In the 10 cultivars tested, the ranges of quality parameters were GPC 11.7–14.0%, WGC 22.0–29.3%, SDS 21.4–35.1 mL, FN 147–363 s, dough stability time 1.7–12.1 min, and peak viscosity 1056–2670 cP. Chuanmai 104, a SHW cultivar with yield level of 9000 kg ha-1, showed the best quality with SDS of 30.3 mL, FN of 325 s, dough stability time of 9.8 min, and final viscosity of 2796 cP. In contrast, Mianmai 367 showed the worst quality with SDS of 24.6 mL, FN of 147 s, dough stability time of 2.2 min, and final viscosity of 827 cP. Besides, germination index (GI) also varied significantly among cultivars. The mean GI of cultivars at physiological maturity stage was 0.31, ranging from 0.06 to 0.76. Chuanmai 104 had the lowest GI value. Our re-sults suggest great potential for quality improvement of Southwest winter wheat, and Chuanmai 104 can be used as a promising parent in breeding programs.关键词
