摘要:
异附加系是重要的种间材料,可用于种间外源遗传物质的渐渗及基因定位等相关研究,创制多种类型的异附加系对于栽培黄瓜(Cucumis sativus)的品种改良及相关研究均具有重要作用。本试验中以来源于酸黄瓜(Cucumis hystrix)和栽培黄瓜‘北京截头’杂交的种间异源四倍体为母本,以‘北京截头’为轮回父本,连续回交获得22株植株。利用基因组荧光原位杂交(GISH)技术确定22株BC2群体中附加有外源染色体的植株,然后利用oligo-FISH技术和12个酸黄瓜染色体单拷贝序列标记准确识别外源染色体。共筛选出4种异附加系材料,包括3种单体异附加系和1种双单体异附加系。其中3种单体异附加系分别附加酸黄瓜6号、10号和12号染色体,双单体异附加系同时附加了酸黄瓜6号和10号染色体。
