胚挽救和分子标记辅助筛选获得番茄抗根结线虫杂种

为获得番茄抗根结线虫杂种,以含有温度敏感型抗根结线虫Mi-1基因的高代优良自交系栽培番茄(Lycopersicon esculentum)5678161"为母本,与含有非温度敏感型抗根结线虫Mi-3基因的秘鲁番茄(Lycopersicon peruvianum)LA2823"为父本进行杂交,通过胚挽救技术获得10个胚挽救苗株系;应用序列相关扩增多态性(SRAP)分子标记技术对胚挽救苗进行亲子鉴定,证实杂种的真实性;利用Mi-1和Mi-3基因的特异引物对杂种植株进行分子检测,从杂种中检测出拥有Mi-1基因标记的后代10株,同时拥有Mi-1和Mi-3基因标记的后代1株....
