多抗病性是提高皮棉产量和纤维品质的关键。我们采用了复式综合杂交,聚集和保持、控制超强度及产量基因的优良特性,选出优良的F_2、F_3,和F_4植株。它们具有提高了的纤维长度(30mm)、纤维强度(40.99—43.84mN)和纤维细度(5300—6060m/g),抗镰刀枯萎病,较耐黄萎病,比对照(川73—27)增产10.1％。其中,选系MAR034已列入1987年四川省区域试验。作者还研究了与棉花多逆抗性育种有关遗传、生理、生化的机理,并应用于育种工作中。研究结果表明,综合效应是显著的。
Multi-disease resistance is the key to improve lint yield and fiber quality. We used the excellent hybrids, hybrids, aggregates, and maintainers that control the super-strength and yield genes and selected the excellent F 2, F 3, and F 4 plants. They had increased fiber length (30 mm), fiber strength (40.99-43.84 mN) and fiber fineness (5300-6060 m / g), resistance to sickle Fusarium wilt, more resistant to Verticillium wilt, than controls (Chuan 73-27) Increase production by 10.1%. Among them, the election system MAR034 has been included in the 1987 Sichuan Province regional test. The author also studied the genetic, physiological and biochemical mechanisms related to the multi-resistance cotton breeding and applied it to breeding work. The results show that the composite effect is significant.
