摘要
通过对中国棉花杂种优势利用研究成功范例的系统分析,认为棉花杂种优势利用的主要途径是人工去雄法,核心技术是确保亲本的遗传稳定,关键环节是提高制种的质量和产量,高产措施是稀植大棵栽培。
The article network analyses our country cotton hybrid vigour utilization by means of the successful model, It also thinks that the main method of cotton hybrid vigour utilization is artificially removing stamen, and to guarrantee the parent heredity is the core technique, and to raise the quality and yield of producing seed is the key sector, and the high yield measure is sparsaly-planting-big-seedling culture.
