空间诱变水稻大粒型突变体的遗传育种研究Studies of Inheritance and Application in Rice Breeding of theLarge Grain Mutant Induced in Space Environment
水稻 突变体 空间诱变 优质 籽粒大小 不饱和回交法
2007/12/29
对粳稻农垦58经空间诱变产生的大粒型突变体进行大粒型性状的遗传分析和育种应用研究。结果表明,大粒型突变体的籽粒大小(以籽粒体积表示)表现为受多基因控制的数量性状。大粒型突变体谷粒细长,具馨香味,外观品质优,对粳稻的亲和性好,是一个罕见的优质米资源。以大粒型突变体为供体,高产、外观米质差的晚粳推广品种为受体,采用不饱和回交结合分离世代糙米外观品质鉴定的方法,将大粒型突变体的优质性状导入晚粳背景,选育...
