摘要
通过对新高抗 5号分别与 70 1 -1、特大铃两个品种进行正反交得到的 F1代及三个亲本和一个对照 (中棉 1 9号 )等八个处理的研究 ,分析了抗虫杂交棉的杂种优势。结果表明 ,抗虫杂交棉具有较强的杂种优势 ,F1代完全抗虫 ,抗病性明显增强 ,生长势变强 ,产量明显提高 ,增产幅度高达 2 0 .5 %以上 ,但纤维长度没有明显优势。研究表明 。
The paper studied on F 1 hybrid of insect resistant cotton and ordinary cotton of expression and genetics. Researches showed that heterosis of F 1 hybrid was obvious and F 1 hybrid possessed to the hiltresistance to worm. Furthermore contradictory was built up and yield was increased and growing was more powerful.But length of fiber lightly shortened. F 1 hybrid is utilized at productiveness.Researches showed best grouping was utilized and generalized.
