河北省行唐县棉花研究所经多年研究,育成了子叶期有标记性状的棉花隐性核不育材料芽黄A,发现了芽黄A的温敏感现象,研究出了大田使用温控繁殖方法,适用于大批量配制一代杂交种,同时育成了配合力高的不育系8748A,选配出了强优势杂交组合,生产上应用一代杂交棉的经济和社会效益大大提高。1 选育过程 1982年春从北京农大引进从陆海杂交后代选出的,以“出苗稍晚、前期发育较迟”为标记的隐性核不育“81A”的不育系种子、杂合可育株自交种子及杂交一代种子试种。发现“216
After many years of research, Xingtang County Cotton Research Institute of Hebei Province bred bud yellow A, a recessive nuclear sterile material with marked trait at the cotyledon stage. The temperature-sensitive phenomenon of bud yellow A was found. , Suitable for the preparation of a large number of hybrid generation at the same time, bred at the same time with a high male sterile line 8748A, matching out a strong hybrid cross combination, the production of a generation of hybrid cotton economic and social benefits greatly increased. 1 breeding process Spring 1982 from Beijing Nongda introduced from the offspring of the cross between the sea and the “emergence of the late, early development is delayed” as recessive sterile “81A” sterile male sterile seeds may hybrid Self-bred seed and cross-breeding seed test.
