豌豆半无叶突变体性状的遗传及在育种上的利用Tendril Inheritance in Semi-leafless Pea and Its Utilization in Breeding
豌豆 半无叶类型 遗传育种
2007/12/30
摘要以半无叶类型、普通类型豌豆为试验材料，对卷须性状的特征特性、遗传规律及在育种上的利用进行了研究。结果表明：半无叶类型豌豆品种卷须极其发达，能够在株间相互缠绕，形成棚架结构，显著地提高了品种的抗倒伏能力，同时改善了群体通风透光性能，显著提高了新品种的产量，是豌豆抗倒伏育种的重要原始材料。半无叶类型属单基因质量性状遗传，显隐性完全，卷须基因af和子叶颜色基因i表现连锁，位于1号染色体上，交换值为5...
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...
