摘要: 为拓宽甘蓝型油菜遗传基础,解决甘蓝型油菜育种中早熟资源贫乏的问题,利用甘蓝型油菜(Brassica napus,2n=4x=AACC=38)与白菜类蔬菜(Brassica campestris,2n=2x=AA=18)的大白菜、小白菜和紫菜苔进行杂交,采用系谱法,经过连续10 年的选择,培育出10 个稳定的早熟优良品系,代号D1~D10。这些新种质的生育期比对照早2.5~9.5 天,品质符合国家双低油菜标准,农艺性状各具特色。由于新种质拥有白菜A染色体的遗传背景,在杂交组合测配中,用这10 个新种质比用非新种质材料配制杂交组合早熟,且获得高产组合的概率高出1倍以上。

Abstract: The study aims to widen genetic basis of Brassica napus and the solve problem of early mature germplasm shortage in breeding. 10 early mature rapeseed germplasms, named D1-D10, were obtained from Brassica napus (2n=4x=AACC=38) hybridized with vegetables of Brassica campestris (2n=2x=AA=18), such as Chinese-cabbage, No-heading Chinese-cabbage and purple Tsai-tai by pedigree method for 10 years. These new gemplasms matured 2.5-9.5 days earlier than CK, accorded with the national quality standards designed for rapeseed and had distinguished agronomic characters. The cross combination of the 10 new germplasms not only had earlier maturity but also had higher yield 1 time more than that of the cross combination of the old germplasms, because these new germplasms had A chromosome genetic background of Brassica campestris.
