抗虫棉品种(系)主要农艺性状配合力与遗传力分析
Analysis on Combining Ability and Heritability of Main Agronomic Characters of Insect-Resistant Cotton Varieties (Lines)
摘要
Abstract
With 12 insect-resistant cotton varieties ( lines) as parents,the F1 generation was obtained by 6 ×6 incomplete diallel cross ( NCⅡ) .The combing ability and heritability of their 8 agronomic characters were analyzed .The results showed that single boll weight and plant height had higher broad -sense and narrow-sense heritability , so they should be chosen in earlier generations .The other characters had higher broad -sense heritability but lower narrow -sense heritability , so they should be selected in latter generations .Jiaxing 6 , Zhong 41 and A48 were the parents with better comprehensive characters .The specific combining ability a-nalysis showed that the better combinations were Zhong 41 ×A49, A1 ×A48, GK44 ×S08 and Jiaxing 6 × S08 .关键词
