利用太谷核不育小麦进行小麦回交育种技术张绍南，张秋英，叶定生（福建省农科院稻麦研究所）一、前言小麦常规育种存在着需要做大量的杂交组合，规模大，包袱重，成功的机率小；通过一次杂交，一般在连锁遗传情况下交换率较低，选择新的基因型机会较少．所需的育种目标无... Backcross Breeding Techniques of Taigu Nuclear Sterile Wheat ZHANG Shao-Nan, ZHANG Qiu-Ying, YE Ding-Sheng (Institute of Rice and Wheat, Fujian Academy of Agricultural Sciences) I. INTRODUCTION There is a need for a large number of crossbreeding combinations in conventional wheat breeding. , The probability of success is small; through one crossing, the exchange rate is generally lower in the case of linkage inheritance, and there is less chance of selecting a new genotype. The desired breeding goal without ...
