低酚棉亲本产量有关性状的遗传研究

摘要:
应用双列杂交法研究低酚棉亲本产量性状的遗传表现。结果表明:陕9702,中13和冀2031为一般配合力较好的优良亲本。结合特殊配合力分析表明,较强杂种优势组合是陕9702×中13,石16×中13和陕9702×冀2031;单株籽棉、单株皮棉、单株铃数一般配合力和特殊配合力效应值均较高。根据遗传力的表现,这些性状在低酚棉育种后代选择中应放在早代进行。

Parent's Heredity of Yield Characters in Glandless Cotton
Abstract:
Based on the diallel cross, the heredity of yield characters in glandless cotton was studies.The results showed that the parents with high general combining ability were Shaan 9702, Zhong 13 and Ji2031. The specific combining ability analysis showed that the combinations with high heterosis were Shaan 9702×Zhong 13,Shi 16× Zhong 13 and Shaan 9702×Ji 2031.The characters with both high general combining ability and specific combining ability were seedcotton/plant, lint yield/plant and boll numbers/plant, and when heritability considered, the characters should be selected early in glandless cotton breeding.
Key words:  glandless cotton,yield character,heterosis,combiningability
