利用10个小麦品种,对单茎库、源及其比值与产量的关系进行了初步研究。结果表明,库性状、源性状与子粒产量的相关性均未达到显著水平,小麦单茎库源比值与产量均呈正相关趋势,穗粒数/旗叶面积、穗粒重/旗叶面积与产量的表型和遗传正相关均达到极显著水平,对各产量构成因素均无明显不利影响,可作为小麦高产育种的重要筛选指标。 Ten wheat cultivars were used to study the relationship between single stalk stock, source and its ratio and yield. The results showed that there was no significant correlation between the traits and the traits of grain yield and grain yield. The correlation between the single-stem and slenderness and yield of wheat was positively correlated with the yield of grain, the number of grain per spike / area of ​​flag leaf, The phenotypic and genetic positive correlations reached extremely significant levels, and had no obvious adverse effect on the yield components, which could be used as an important screening index for high-yielding wheat breeding.
