在棉花杂交制种方法研究上,由于选用的亲本材料不同,所以采取的制种途径也有所不同,但各种制种方法各有特色,现对各种制种方法作一简要评价。 1 人工去雄授粉杂交制种 此方法研究最早,而且最为成熟,是目前最为常用的方法。由原来的选花杂交,挂线标记,改进为现在的去早、晚蕾,集中时期,全株制种,每667m~2产量由原来40～60kg提高到现在90～110kg。用此种方法选配杂交组合,亲本不受限制,选配自由,较容易筛选到高优势杂 In the research of hybrid cotton seed production methods, the methods of seed production are different because of the different selection of parent material, but all kinds of seed production methods have their own characteristics. Now, we make a brief evaluation of the methods of seed production. An artificial to male pollination hybrid seed This method was first studied, and the most mature, is the most commonly used method. From the original hybrid flowers, hanging line marking, improvement for the present to early, late bud, concentrated period, whole plant seed production, every 667m ~ 2 output from the original 40 ~ 60kg increased to now 90 ~ 110kg. In this way matching hybrid combinations, the parent is not limited, matching free, easier to screen high-heterosis
