| 摘 要： | 以来自野生番茄Solanum pennellii LA716渐渗系群体包含果实耐压QTL的12个渐渗系为试验材料,通过与加工番茄M82杂交获得杂交一代,即ILH(Introgression line hybrid),通过渐渗系间不完全双列杂交获得杂交一代,即ILab(Introgression line a×Introgression line b),采用平板挤压法测定红熟番茄果实耐压力,试验结果表明,其耐压QTL表现出超显性、显性和加性效应遗传,QTL的互作也同样表现出超显性、显性和加性效应。包含在IL 8-2-1上的1个QTL(Crf8)和杂交组合IL 10-3×IL 8-2-1(即Crf10+Crf8)的遗传互作有待于进一步试验验证。

| Abstract: | Tomato fruit firmness was investigated by using 12 introgression lines derived from the wild tomato species Solanum pennellii LA716.First filial generation which was assigned as ILH (Introgression line hybrid) was obtained by crossing ILs with the processing tomato M82 and ILab (Introgression line a × Introgression line b) was gained by incomplete diallel design method.Fruit firmness was tested by flat-plate compression.Our results showed that the QTL and their interaction for tomato red fruit firmness were inherited as over-dominant,dominant as well as with additive effect.The QTL interaction of Crf8 harbored by the IL 8-2-1 and the combination of IL 10-3 × IL 8-2-1 (Crf10 + Crf8) need further confirmation. |
