摘要: 以培育的14 个玉米新系为材料,对幼胚的Ⅱ型愈伤产率和愈伤再生率,以及幼胚和农杆菌共培养后幼胚的GUS 瞬时表达率进行统计,据此判断不同自交系在组织培养中的潜力,及其是否为农杆菌的易侵染材料,最终试验选出了zpm5 和zpm6两种既适合组织培养又对农杆菌敏感的基因型材料。在对成熟胚愈伤诱导率的统计中发现,成熟胚愈伤诱导率可以作为对幼胚愈伤诱导的预测手段,两者的愈伤诱导率呈正相关性。

Abstract: At present, Agrobacterium mediated genetic transformation in maize is widely used in the world. A good recipient material isvery important for the transformation system. In this study, 14 new inbreed lines were used to choose the suitable recipient material by analysingembryogenic Type Ⅱ callus induction, plant regeneration rate and GUS transient expression. Zpm2 and zpm5 were finally screened for maizetransformation system. In the study of mature embryos callus induction, mature embryos callus induction rate can predict the growth status ofimmature embryos callus and their callus induction show a positive correlation.
