小麦株高、旗叶和穗部性状的遗传特性及相关分析
Genetic characteristics and correlation analysis of plant height,flag leaf and spike traits in common wheat
摘要
Abstract
The variation coefficient and correlation of plant height,flag leaf length,flag leaf width,spikelet number and kernel num-ber per spike of the main stem in 20 wheat(Triticum aestivum L.)varieties planted in Hubei Province were analyzed.The results indi-cated that the variation coefficients of plant height and spikelet number were small,suggesting high genetic stability.Conversely,the variation coefficient of degenerate spikelet number was larger,indicating a more significant influence from the environment.There were varying degrees of correlation among the traits.The single-spike weight had a highly significant positive correlation with flag leaf length,flag leaf width,kernel number per spike,spike length and spikelet number(P<0.01),while it had a highly significant nega-tive correlation with degenerate spikelet and neck length of spike(P<0.01).Degenerate spikelet number and neck length of spike also had a significant negative correlation with kernel number per spike and spikelet number(P<0.05).关键词
