摘要
通过第一次收花率、生育期、营养生长期与生殖生长期比较等性状总结了我国短季棉早熟性育种的成效.对不同年代短季棉品种的基因型值分析表明,短季棉生育期缩短9~14 d,本试验不同年代品种平均缩短2.5 d.通过对早熟性多个性状的对比,分析了辽棉系列短季棉与中棉所系列短季棉的不同育种策略.
Through compared the first harvest cotton index and growth and the vegetative period and the reproductive period and so on, we sum up the earliness breeding achievements of short season upland cotton in China. Analyzed the genotype value of the different short season upland cotton variety, the results indicated that the short season cotton growth reduces 9 to 14 days, the varieties in different decades meanly reduced for 2.5 days. The many other earliness traits were compared too. The different breeding strategies were analyzed in the CCRI cotton variety series and the Liao cotton variety series.
