杂交棉中棉所57号F1和F2代产量构成及纤维品质性状空间分布比较
Comparative Study of the Yield Components and Fiber Quality Spatial Distribution of F1 and F2 of Insect-Resistance Hybrid Cotton Zhongmiansuo 57
摘要
Abstract
[Objective]The aim was to provide theoretical basis to make a better use of F2 generation insect-resistance hybrid cotton. [Method] Using F1 generation of Zhongmiansuo 57 which was planted wide optimum in the south of Xinjiang and F2 generation hybrid cotton seeds breeded by F1 as test materials, by dint of three kinds of planting density, six bell bits, according to "cotton germplasm describe norms and data standard" for its economic characters and fibre quality agricultural the investigation, identification and evaluation, the yield of F1 and F2 generation of insect-resistance hybrid cotton was compared. [Result] The results showed that, in the aspects of boll weight and lint, spatial distribution of seeds, the competitive advantage of F2 generation weakened slightly compared with F1 generation. As for the fiber quality performance, F2 generation separation caused the downward trend, but without significant differences. [ Conclusion] In the end, the density of F2 generation plant was around 225 000 plants/hm2 and the density of F1 generation plant was about 180 000 plants/hm2.关键词
