摘要
棉花杂交育种的主要方法有人工去雄法、核不育两系法、核不育三系法、胞质不育三系法等。棉花杂交制种要解决的技术关键有:制种方法有待重大突破,杂种优势有待进一步提高。随着生物尖端技术在棉花杂交育种上的广泛利用,将促进棉花杂种优势广泛利用。
The main methods of cotton cross breeding are artificial emasculation, genie male sterile two - line, genic male sterile three - line, cytoplasmic male sterility three - line and so on. The key techniques of cotton hybrid seed production： the methods of preparation seeds to be a major breakthrough, hybrid vigour to be further improved. The cotton hybrid vigour will be abroad utilized as the extensive use of biological sophisticated technique in cotton cross breeding.
