概述了国内外棉花杂种优势利用研究现状。肯定了利用各种有特色的棉花新材料 (抗病、抗虫、耐逆等 )与适应性好的优良推广品种配制组合 ,其F1和 F2 在逆境条件下 (病、虫、旱等 )增产潜力大。目前的杂交制种仍以人工去雄及核雄性不育系的利用为主 ,应加强化学杀雄剂的筛选及通过抗虫不育系的培育 ,实现昆虫传粉 ,真正达到简化制种的目的。
The current situation of utilization of cotton heterosis in China and abroad is summarized. Affirmed the use of a variety of new features of the new cotton materials (resistance, insect resistance, tolerance, etc.) and good adaptability to promote good variety combinations, the F1 and F2 under adverse conditions (disease, insects, drought, etc.) Great potential. At present, the hybrid seed production is still dominated by man-made and male-sterile male sterile lines. Screening of chemical maleaters and breeding of insect-resistant male sterile lines should be strengthened to achieve insect pollination so as to achieve the goal of simplified seed production .
