中文摘要: |
籼粳交是扩大遗传基础和选育突破性品种的重要手段,粳型亲籼系在籼粳交育种中具有独特的地
位。粳型亲籼系指具有籼型花粉不育基因型的粳型品系,1994 年由张桂权首次提出,粳型亲籼系培育成不育
系并成功组配了籼粳型杂交稻;梳理了粳型亲籼系与广亲和、特异性亲和、籼粳型杂交稻、籼粳型常规稻、粳
型亲籼系、掺粳籼稻、籼粳架桥等的关系。粳型亲籼系不能作为常规稻品种的原因是粳型亲籼系的培育效率低
下,难以应用于常规稻育种的原因是粳型亲籼系培育效率低下和较小的育种规模,但在籼粳交育种规模扩大
的情况下,粳型亲籼系在常规稻育种中显现出重要的利用价值,阐明了如何发挥其价值的育种策略,利用粳型
亲籼系培育掺粳籼稻品种的育种效率高,初步开展了粳型亲籼系的选育。 |
英文摘要: |
Indica-japonica crossing is a powerful approach to broaden genetic basis and develop elite variety,
indica-compatible japonica line is situated a special position in indica-japonica crossing breeding. Indica-compatible
japonica line is japonica line with indical S type,the concept was put forward by Zhang gui-quan in 1994,the line
was developed as A line in indica- japonica hybrid. The relations between indica-compatible japonica line with other
concepts such as wide-compatibility,specific compatibility,indica- japonica hybrid,indica- japonica varity,indica
rice introgressed by japonica rice were distinguished. The reason why indica-compatible japonica line couldn’t be
qualified as a registered variety is the low efficiency of development of indica-compatible japonica line,the difficulty
of application of indica-compatible japonica line in inbred rice breeding is the low efficiency of development of indicacompatible
japonica line and small scale of concerned breeding. The line is actually important in large-scale indicajaponica
crossing breeding. The approach to apply the line was expounded. The efficiency to develop indica rice
introgressed by japonica rice via application of indica-compatible japonica line,the breeding for indica-compatible
japonica line was carried out preliminarily . |
