| 摘 要： | 采用4 份耐热性不同的茄子亲本半轮配法配制4 ×4 双列杂交, 对P1 、P2 、F1 、F2 、BC1 等5 个世代四叶期幼苗在温室内进行高温(平均昼/ 夜温度38. 8/ 24. 2 ℃) 处理, 同期田间栽培(平均昼/ 夜温度34. 4/ 22. 6 ℃) 。采用Hayman’s 法分析苗期耐热指数和成株期坐果率的调查数据, 表明, 茄子耐热性为不完全显性遗传, 受两对以上基因控制, 符合加性—显性模型, 其中加性效应占更主要成分。据此提出了耐热性选择方法。

| Abstract: | The inheritance of high temperature tolerance (HT) in eggplant was studied with 4 ×4 half-diallel crosses, which derived from four parents with different tolerance to high temperature. Two parents and their progeny of F1 , F2 and BC1 involved in present experiment were simultaneously treated by high temperature in greenhouse and open field. HT index and ratios of fruit setting were respectively collected following Hayman’s procedure. The results showed that inheritance of HT in eggplant is of incomplete dominance that fits in with a model of additive-dominance , and additive effects play more important roles on HT than dominant effects do. Furthermore , selecting methods for improving HT of eggplant were suggested. |
