利用SSR分子标记技术构建3个特早熟甘蓝型油菜恢复系的指纹图谱,筛选出这3个恢复系的共显性SSR标记,测定了这3个恢复系的异交率。结果表明,恢复系材料4395、3509、4152的异交率分别为46.02%、33.32%、18.12%,在P<0.01时呈极显著差异,说明这3个恢复系的异交差异明显,为确定这3个恢复系在综合杂交种中的比例提供依据。 The SSR markers were used to construct the fingerprints of three elite early-maturing rapeseed restorer lines, and the co-dominant SSR markers of these three restorer lines were screened out. The outcrossing rates of the three restorer lines were determined. The results showed that the outcrossing rates of restorer lines 4395, 3509 and 4152 were 46.02%, 33.32% and 18.12%, respectively. There was a significant difference at P <0.01, indicating that the outcrossing rates of the three restorer lines were significantly different The three restorers provided the basis for the proportion of hybrids.
