摘要
[目的]在短季棉育种实践中达到性状选择的统一和平衡.[方法]为提高抗虫短季棉育种成效,以1998 ～ 2009年国审及省审的11个品种为材料,对其主要性状及性状之间的相互关系进行了分析.[结果]短季棉品种将早熟、高产、优质集于一身是可能的,是其多个性状协调配合的结果;形态性状选择可作为短季棉选育的一个重要手段;短季棉的抗病性还有待提高.[结论]该研究可为减少今后短季棉育种的盲目性提供参考依据.
[ Objective] The aim was to reach the unity and balance of characters selection during short season cotton breeding. [ Method] For improving the breeding effects of insect-resistant short season cotton, 11 cotton varieties authorized by national or provincial committee in 1998- 2009 were used to investigate the relationship among different characters. [ Result] It is possible that short season cotton could integrate with ear- ly maturity, high yield and quality, and become a coordinating type of all characters. Morphological characters selection can be used as an impor- tant means for short season cotton breeding. On the other hand, disease resistance of short season cotton should be improved. [ Conclusion] The study provides a reference basis for reducing the breeding blindness of short season cotton in the future.
