【摘要】 [目的]选育品质优良、综合性状好、配合力强的不育系。[方法]利用引进种植的品系03P27中的雄性不育单株,采取田间选择和品质筛选相结合,不育株后代连续回交的方法对其进行选育。[结果]育成甘蓝型油菜双低不育系六020327A,经田间性状鉴定表明,属细胞质雄性不育系。该不育系芥酸含量0.3%,硫甙含量26.68μmol/g,含油量达40.69%;其育性对温度反应比较迟钝,高温败育彻底;具有田间性状好、长势强、抗逆性和配合力较强等特点。[结论]不育系六020327A是开展优质杂交油菜品种选育的重要材料。更多还原

【Abstract】 [Objective]The Brassica napus L.CMS with good quality,good integrated traits and strong combining ability was bred.[Method] The individual plant of male Brassica napus L.CMS from rapeseed line-03P27 introduced was successively selected with the combination method of field investigation and quality-testing and the backcross of its single sterile plant.[Results] The double-low brassica napus male-sterile line-Liu 020327A was bred and it was the cytoplasm male-sterile line after the field character appraisal.The content of its erucic acid was 0.3%;sulfur glycoside,26.68 μmol/g and oil,40.69%.The response of its fertility to temperature was relatively slow and its abortion under the condition of high-temperature was complete.The CMS line had good field character,vigor growing,high resistance and strong combining ability.[Conclusion] The CMS line was important material of high-quality hybrid rape breeding.更多还原
