甘蓝型油菜特异矮秆直立株型新品系DW871株高的遗传分析
Genetic analysis of plant height in new dwarf line DW871 of Brassica napus L.
摘要
Abstract
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.关键词
