应用植物数量性状主基因+多基因混合遗传模型多世代联合分析方法，研究了甘蓝型油菜浙平1号×04Pb11(I)和宁1243×04Pb11(II)的P1、P2、F1、B1、B2和F2 6个世代初花期单株抗压力的遗传。结果表明：抗倒伏性状的遗传在组合I受2对加性-显性-上位性主基因+加性-显性-上位性多基因控制，在组合II受2对加性-显性-上位性主基因+加性-显性多基因控制；2个组合中的2对主基因都以加性...
将四倍体大青口(B.pekinensis,aaaa,4x=40)与红甘蓝(B.oleraceavar.rubra,cc,2x=18)杂交获得的倍半二倍体(aac,3x=29)自交、分离(A),在后代中选择外型酷似胜利油菜(B.napus var.oleifera,aacc,4x=38)的个体。鉴别染色体组型后确定有3个植株为欧洲油菜类型(aacc,4x=38)。将大青口与红甘蓝的倍半四倍体(aaa...

一种花色突变雄性不育油菜的发现The Discovery of a Novel Flower Color mutation in Male Sterile Rapeseed( Brassica napus L. )
甘蓝型油菜 花色 嵌合 白化 突变 雄性不育
2008/1/8
摘要
在甘蓝型油菜杂交种C022（母本为由3对基因控制育性的隐性细胞核雄性不育系9012A）不育株开放受粉的后代中，发现一种稀有的黄白双色嵌合花瓣的甘蓝型油菜突变体991S。其具有3个形态特征：（1）4片花瓣每片中央均为条带状黄色色斑，而两侧为白色，为嵌合双色花瓣；（2）4片花萼也可发生中间条带状白化；（3）目前只在不同群体的雄性不育株中出现，与同源的黄色花不育株形态相似，植株纤细矮小，花器也较...
通过遗传差异较大的2个甘蓝型油菜（Brassica napus L.）纯系亲本组合（HSTC14×宁油7号）衍生后代的世代家系群体分析，应用主基因+多基因家系世代联合分离分析方法研究油菜千粒重的遗传体系。结果表明，甘蓝型油菜HSTC14×宁油7号组合千粒重遗传体系系由一对主基因+多基因构成，主基因中只有加性效应(d = 0.1062),不存在显性效应;多基因存在加性([d] = 0.2228)和显...
