苏联乌兹别克科学院植物生理研究所科研人员,针对当地农业存在问题,为进一步提高棉花产量进了大量应用科学研究。首先,棉花育种工作者利用对凋萎病具有一定免疫能力的墨西哥野生棉,与当地栽培早熟、高产、纤维品质好、不抗凋萎病棉花品种司—4727进行杂交,育成了抗凋萎病、高产塔什干棉花新品种,实现了全苏第五次换种,棉花产量超历史记录。为尽快推广早熟、抗凋萎病、高产塔什干棉花新品种,须研究改进栽培技术措施,例如,改进耕作制度,推行轮作、机械化和化学化,使乌兹别克棉花产量从1970年的26.3公担/公顷,提高到1980年的33.2公担/公顷,籽棉收购量
Researchers at Institute of Plant Physiology, Uzbek Academy of Sciences, Soviet Union, aiming at the problems in local agriculture, and applied a large number of applied scientific researches to further increase cotton yield. First, cotton breeders developed resistance to wilts disease by using Mexican cotton that is resistant to the wilt disease and crossed with a cotton cultivar variety, 477, which is a locally cultivated, precocious, high-yielding, fiber-quality, non- , Yielding a new variety of high-yielding Tashkent cotton and achieving the fifth transestation in the entire Soviet Union with a record-breaking cotton output. In order to promote early maturity, resistance to wilt disease and high-yielding new varieties of Tashkent cotton, it is necessary to study measures for improving cultivation techniques such as improvement of the farming system, rotation, mechanization and chemicalization so that cotton output in Uzbekistan will rise from 26.3 kg / ha in 1970 , Up to 33.2 km / ha in 1980, the purchase of seed cotton
