研究结果表明：品种对铃重影响作用表现为中早熟品种大于中熟品种，品种间差异随育苗期延后而增大。中早熟品种棉纤维发育早于中熟品种。品种对棉籽（仁）脂肪累积作用表现为中早熟品种优于中熟品种，而蛋白质累积则相反。棉仁棕榈酸、油酸、硬脂酸含量变化品种间差异较小，豆蔻酸和亚油酸变化趋势相反，品种间存在差异；品种对棉仁氨基酸累积的作用表现为中熟品种优于中早熟品种。３∶１式移栽棉品种选择受育苗期影响很大，早育苗时可选用中熟品种。
The results showed that the effect of varieties on boll weight was more obvious in middle-early maturing varieties than in middle maturing varieties, and the differences among cultivars increased with the delay of seedling emergence. Middle-early maturity varieties of cotton fiber development earlier than medium-maturing varieties. The accumulation of cottonseed (kernel) fat in cultivars showed that middle-early-maturing varieties were better than middle-maturing varieties, while the protein accumulation was the opposite. Cotton linolenic acid, palmitic acid, oleic acid, stearic acid content changes between varieties is small, myristic acid and linoleic acid changes in the opposite trend, there are differences between varieties; cotton varieties of amino acid accumulation of medium maturity varieties are better than in Early varieties. 3: 1 transplanting cotton varieties are subject to a great influence on the seedling stage, early maturing medium maturing varieties can be used.
