为全面了解我国高粱杂交种主要性状变迁,对1970年以来的60份高粱主推杂交种的生育期、株高、穗长、千粒重等4个农艺性状和蛋白质、粗脂肪、粗淀粉、单宁含量等4个品质性状分来源和年份进行了多样性分析。结果表明,不同来源杂交种农艺、品质性状差异明显。不同年份杂交种的农艺性状有显著差异,品质性状中粗淀粉和单宁含量有显著差异,蛋白质和粗脂肪含量差异不显著,农艺性状的变异大于品质性状。
In order to fully understand the changes of main traits of sorghum hybrids in China, the effects of four agronomic traits and protein, crude fat, crude starch, tannin content Four quality traits, such as source and year, were analyzed for diversity. The results showed that the agronomic and quality traits of hybrids from different sources were significantly different. The agronomic traits of hybrids in different years were significantly different. There were significant differences in the contents of crude starch and tannin among the quality traits, but not significant in the contents of protein and crude fat. The variation of agronomic traits was greater than the quality traits.
