杂交水稻的双亲在熟性遗传上,有人认为迟熟亲本往往表现为显性。但没有明确指出熟性的遗传规律。由于没有掌握熟性的传递力,在选择亲本时往往盲目性较大,结果事倍功半。近几年来,我们在广泛的测交材料和配合力测定试验中,开始注意观察分析遗传传递力,希望从中找出一些规律耒指导杂交水稻的育种工作。 The parents of hybrid rice in the inheritance of maturity, some people think late-maturing parents tend to show dominant. But did not specify the genetic law of maturity. Because they do not grasp the transfer of maturity, they often blindly choose their parents, resulting in less effort. In recent years, we began to pay attention to the analysis and analysis of genetic transmission force in a wide range of test materials and combining ability tests, hoping to find out some laws and guide the breeding of hybrid rice.
