对173份甘蓝型油菜DH系材料主要农艺性状、品质性状以及SSR分子标记的分析表明,DH系系内性状表现高度一致。农艺性状中,分枝高度的变异系数最大(26.39%),株高的变异系数最小(9.42%);品质性状中,芥酸含量变异系数最大(62.86%),含油量的变异系数最小(5.10%)。SSR分子标记分析发现,DNA谱带符合1∶1分离规律。
Analysis of the main agronomic traits, quality traits and SSR molecular markers of 173 DH lines from Brassica napus showed that the traits in DH lines were highly consistent. Among the agronomic traits, the coefficient of variation of branch height was the highest (26.39%) and the coefficient of variation of plant height was the lowest (9.42%). The coefficient of variation of erucic acid content was the highest (62.86%) and the coefficient of variation %). SSR molecular marker analysis found that DNA bands in line with 1: 1 separation law.
