摘要
江苏省的常规粳稻育种在国内外具有一定的影响与成就。如何在现有基础上提高品种的增产潜力并改进其品质,以取得突破性进展?其育种的至关点仍然是亲本资源选配问题。具体应从5个方面入手:1.拓展范围,合理选用;2.注重中间材料的利用;3.特异种质资源的利用;4.加大亚种间材料的利用份量;5.选配方法的改进。同时,在杂交配组时,应结合育种目标,综合考虑品种形成的内外因素,育成高质量、高起点的新品种。
Breeding of conventional keng rice of Jiangsu province is making a fair influence and achievement at home and abroad. How to improve increasing yield potential and make a breakthrough? The key problem of its breeding still is selected mating of parent resource. The details are as follows. 1. Develop range, select reasonably; 2. Lay stress on utilization of intermediate material; 3.Put germ plasm to rational use; 4. Further use subspecies material; 5. Improve the way of selected mating. Simultaneously, in cross combination, the internal and external causes of forming varieties should be considered combining breeding objectives to breed new varieties with high quality and high starting point.
