变异系数

Results showed that variability coefficients of the boll number per plant were the biggest under different ecological environment.Correlative degree analysis indicated that boll weight was the leading factor restricting the boll number;lint index was one of the major factors that affected boll weight,lint percentage and seed index;seed index was the primary factor restricting lint index.Results of path analysis sho...

结果表明，不同生态环境下单株成铃的变异系数最大；关联度分析表明，铃重是制约株铃的主导因素，衣指是制约铃重、衣分及子指的主导因素，子指是制约衣指的主导因素；通径分析结果表明，株铃对籽棉产量的综合直接作用最大；偏相关分析表明，单株成铃、单铃籽棉重、衣分3个产量因素性状对产量的贡献率占总决定度的77.16%，基本上反映了产量因素的构成情况。
