新疆麦套棉品种筛选试验初报

通过对新疆麦棉套作各品种(系)间生育特性和产量品质的比较研究表明,中棉所35号有效结铃期长,产量高,但纤维品质较差; KB-85早熟、单株成铃多,蕾铃脱落率低,衣分,皮棉产量高,纤维马克隆值偏大,成熟度最好,棉纤维长度和强度适中. 98-46和98-28虽然株型紧凑,纤维品质较佳,但由于蕾铃脱落率高等原因,导致最终产量低,不适合套作种植;新陆早10号生育期最短,产量和纤维品质表现一般.综合比较分析,适宜新疆麦棉套种的棉花品种(系)是KB-85 和中棉所35号.

Initial Report on Screening of Relay Intercropped Wheat-cotton Varieties of Xinjiang

The studies on the characteristics of growth and qualities of varieties planting relay intercropping of wheat and cotton have been conducted in Xinjiang. The comparative studies on the characteristics of growth and yield qualities of different v.arieties of relay intercropping wheat and cotton showed that Zhongmian 35 has longer effective boiling stage, with high yield, but poor quality of cotton fibre; KB - 85 has the characteristics of early maturity, with more bells per plant, with low abscission rate of cotton buds and bolls, high yield of lint and lint yield, great Maerom value of fibre, best maturity and moderate length and strength of cotton fibre. Although the number of fruit branches and fruit noates was maximum, there was low ratio of solid fruit on cotton plant. 98 - 28 variety belonged to short- small type one,with high abscission rate of cotton buds and bolls which reached 82% .Xinluzao 10 with the shortest growth duration has moderate yield and fibre quality. By comparative analysis, the KB - 85 cotton variety and Zhong - mian 35 were worth being popularized in large area in Xinjiang.
