Analysis of Agronomic Characters of Chuanzamian 17

用四川省农科院经济作物育种栽培研究所创制的新型完全核不育系MAr为母本,以优质抗虫品系R36为父本,选育的川杂棉17号,在四川省区域试验和生产试验中皮棉产量分别比对照增产24.5%和23.1%,抗枯萎病耐黄萎病,抗棉铃虫抗红铃虫。结果分析表明,川杂棉17号丰产性、稳产性、抗逆性、纤维品质均属很好的优良杂交种,而且其杂交种子生产方法简化,具有很好的推广应用价值。

Chuanzamian 17 was derived from a restorer line R36 and a new complete genetic male sterile line MAr.It was registered in Sichuan Province in March 2008.In the Sichuan Province regional test and production test,the lint yield of Chuanzamian 17 were higher than that of the control and increased by 24.5 % and 23.1 %,respectively.The results showed that Chuanzamian 17 had such advantages as high lint yield,yield stability,excellent quality and special resistance,and the hybrid seeds production processes was simple.
