正确地选择亲本配组,是杂交育种成功的关键。由于水稻亲本的遗传传递规律复杂,至今尚未被摸清,所以组配的盲目性很大,成功率较低,一般很少超过2%。如何减少组配的盲目性,各地育种单位都正在探索。现结合我们的实践,提出一些亲本选择和配组的意见。一、主要水稻良种的亲缘分析三十多年来,我地区试种推广表现较好、种植面积较大的水稻品种有:早籼的莲
Proper selection of parents with the group, is the key to the success of hybrid breeding. Due to the complexity of the genetic transmission of rice parents, which has not yet been ascertained, so the blindness of the allocation of a large, low success rate, rarely exceeding 2%. How to reduce the blindness of teamwork, breeding units all over the world are exploring. Now combined with our practice, put forward some parents to choose and team comments. First, the kinship analysis of the main rice varieties Over the past 30 years, I try to promote better performance in the region, the larger planting area of rice varieties are: early indica lotus
