摘 要:为了探讨与国际接轨的棉花良种繁育的科学方法,通过比较分析中国棉花良种繁育技术发展经历的引种技术、基于群体混合选择的块选和片选技术、基于单株选择的"三年三圃制"及其衍生技术和基于重复繁殖为理论基础的四级种子生产技术,总结了中国棉花良种繁育规模化的3个发展阶段,从人工投入、资金投入和推广规模3个方面阐述了不同良种繁育体制的综合效益,提出了中国棉花良种繁育技术存在问题和发展趋势,认为四级种子生产程序是适合中国国情的科学的良种繁育技术。In order to study scientific method of cotton seed reproduction acting on international convention, this paper compared and analyzed development of techniques in cotton seed production from seed import, field lump selection and piece selection based on population mixed selection, "Three-Nursery in Three Years" as well as its related techniques based on single plant selection, and Fore-Grade Seed Reproduction (FGSR) System technique based on replication selection theory. The three development stages of cotton seed production in scale in China were summarized in this study. The synthesized benefit of different seed production systems were also stated from manpower input, capital input and industrialization scale. FGSR system technique was more scientific seed production techniques suitable for China situation. The challenge and development prospect in seed production in China was also discussed.
