甘蓝型油菜特异矮秆直立株型新品系DW871株高的遗传分析
|
摘要
紧凑株型是油菜抗倒性和稳产性的重要因素。新型矮秆甘蓝型油菜材料DW871具有花序花蕾呈散生状的类甘蓝花序特征,花序或果枝从初花直至收获均表现挺直不弯曲,不串枝,果枝中偏短,着果密,茎秆坚硬,株型紧凑,抗倒性特强等辅助标记性状。本研究分别以DW871为父母本,通过构建不同世代的群体对该品系的株高性状进行遗传分析,辅以其它标记性状进行验证。结果表明源自DW871株高性状为1对显性主基因控制,不存在细胞质效应,但是存在修饰基因的影响,表现出数量性状的遗传特征。DW871为适宜机械化或轻简化种植的中矮秆甘蓝型油菜新品种的选育提供了新的种质资源。
Plant architecture is one of the key factors related to lodging resistance and yield. The dwarf and compact plant architecture has substantial significance in accelerating the yield of rapeseed. The new dwarf line DW871 had more advantages than the wild type rapeseed in marked characterizations,including the similar inflorescence growth characteristics and flowering habits with the cabbage,the straight inflorescences or branches during the whole development stages,short branches,high density of siliques,rigid stems,compact plant type and lodging resistance,and so on. In this study,the inheritance of plant height was analyzed in the different gene rations selected from the crosses between the parent DW871 and other accessions,which were further identified by other marked traits. The results showed that the plant height of DW871 showed the typical quality trait characterization,which was determined by one dominant gene with no cytoplasmic effects. In addition,the plant height of DW871 was affected by modifier gene and conformed to the quantitative traits characteristics. The line SW871 provided the novel rape germplasm resources for selecting the semi-dwarf rapeseed cultivars suitable for mechanizedharvesting and simplified planting.
