“湘无74”是我所用杂交方法育成的一个早熟、丰产、优质、抗逆力强、低棉酚的无棉毒素棉新品种。生产力表现在1982—1984年参加湖南省棉花品种区域试验中,1982年八个试点汇总结果,平均亩产皮棉63.25公斤,比常规棉对照岱红岱增产6.13%,居第二位。1983年八个试点,因有四个试点严重鼠害影响产量,无鼠害四点平均亩产皮棉75.02公斤,居首位,比常规棉对照湘4108增产3.87%,差异达0.05水准。1984年九个试点,其中八个试点参加资料汇总,包括鼠害影响在内,亩产皮棉80.55公斤,为
Xiang-74 was a precocious, high-yielding, high-quality, low-glucosinolate cotton-free toxin cotton variety bred by the hybridization method I used. Productivity performance In 1982-1984 participated in the regional trials of cotton varieties in Hunan Province, 1982 eight pilot summary results, an average of 63.25 kg of lint per mu, compared with conventional Dai Dai Dai cotton yield 6.13%, ranking second place. In 1983, there were eight pilots affected by four experimental rodent pests. No rodent four-point average yield of lint 75.02 kg, ranking first, than the conventional cotton control 4108 yield 3.87% difference of 0.05 level. Nine pilot projects in 1984, of which eight participated in the pilot data collection, including the effects of rodent pests, including 80.55 kg of lint per mu
