摘要: 通过选配11个葡萄杂交组合,探究不同亲本基因型、胚发育培养基中不同玉米素(zeatin,ZT)浓度和不同类型畸形苗的转化对多倍体葡萄胚挽救效率的影响。结果表明:在胚珠发育阶段,添加0.5 mg · L-1 ZT时,杂交组合红宝石无核 × 蜜光的胚发育率(58.89%)和成苗率(22.22%)最高;胚萌发试验中,9个杂交组合的畸形苗发生比例(40.04% ~ 80.04%)均显著高于正常苗,其中子叶白化和多子叶畸形苗类型占比最高,分别为25.29%和24.13%;对不同畸形苗转化培养后,单子叶和多子叶畸形苗转化效率最显著,分别为52.79%和50.13%,子叶筒状畸形苗则不能转化为正常苗,最终11个杂交组合共获得489株杂种植株;筛选出‘红宝石无核’‘火州翠玉’‘底莱特’适宜作母本材料,‘蜜光’和‘大粒玫瑰香’适宜作父本材料。表明通过优化胚挽救技术和畸形苗转化策略,可有效提高三倍体葡萄胚挽救效率和成苗率。

Abstract:

The effects of different parental genotypes,varying concentrations of ZT(Zeatin)in embryo development media,and the conversion of different types of abnormal seedlings on the efficiency of triploid embryo rescue were investigated. Eleven hybrid combinations were selected. The results showed that during the ovule development stage,the addition of 0.5 mg · L-1 ZT resulted in the highest embryo development rate of 58.89% and the highest seedling formation rate of 22.22% in the cross combination Ruby Seedless × Miguang,in terms of embryo germination,the proportion of abnormal seedlings was significantly higher than that of normal seedlings in nine cross combinations,with abnormal seedlings accounting for 40.04% to 80.04%. Among these,cotyledon albinism and polycotyledon abnormalities were the most prevalent,accounting for 25.29% and 24.13%,respectively. After conversion culture of different types of abnormal seedlings,the conversion efficiency was most significant for monocotyledon and polycotyledon abnormalities,at 52.79% and 50.13%,respectively,while tubular cotyledon abnormalities could not be converted into normal seedlings. Ultimately,489 hybrid plants were obtained from the 11 cross combinations,with Ruby Seedless,Huozhou Cuiyu,and Delight identified as suitable maternal materials,Miguang and Dali Meiguixiang as suitable paternal materials. By optimizing embryo rescue techniques and abnormal seedling conversion strategies,the efficiency of triploid grape embryo rescue and seedling formation rates can be effectively improved.
