摘要
采用常规杂交方法,以芥蓝为母本,以甘蓝种的不同变种为父本进行杂交,从F2中选择优良单株,经回交和多代连续自交,最终创制出紫色性状(肉质茎、叶片、叶脉、花蕾)、蜡粉性状(无蜡粉肉质茎、无蜡粉叶片)、肉质茎形状(短纺锤形、柱形)、侧薹性状(早发、多发、颜色紫色或绿色)以及花瓣颜色(浅黄色)等不同类型的芥蓝新种质。应用这些材料成功选育出京紫1号、京紫2号、京紫3号、21M2芥蓝和22M4芥蓝等芥蓝新品种。研究结果为芥蓝种质资源创制提供了科学依据,为芥蓝新品种选育奠定了基础。
Took conventional hybridization technique,and made different combinations which Chinese kale as the female parent was crossed with different subspecies of Brassica oleracea as the male parents.Excellent plants were selected from F2 progenies,then they were backcrossed and self-crossed through several generations,which were used to create new germplasm resources,such as purple trait(fleshy stems,leaves,veins,buds),wax powder trait(waxless fleshy stem,waxless leaves),shape of fleshy stem(short spindle shape,columnar shape),sub-stem trait(early bolting,multiple bolting,purple or green color),flower petal color(light yellow color).New varieties of Chinese kale with different types were successfully bred by using these new materials,including‘Jingzi No.1’‘Jingzi No.2’‘Jingzi No.3’‘21M2 jielan’and‘22M4 jielan’.This study provides a basis for new germplasm resources creation in Chinese kale,and establishes the foundation for breeding new Chinese kale varieties.
