用含 Tm-2nv 基因的“矮黄”为中心亲本,与以适当的番茄品种作为父本,配制成9个杂交组合,以期选育抗 TMV 的番茄杂种一代。研究中采用同亲回归分析方法,并估算配合力、遗传力等遗传参数。试验结果表明,“矮黄”具有很高的配合力,尤其表现在早期产量和总产量,是一个优良的杂交亲本。并评价比较各杂交组合,初步选出矮黄×早粉二号、矮黄×宁红二号和矮黄×汉因茲三个组合。
Using the “Dwarf Yellow” with Tm-2nv as the center parent, nine hybrid combinations were made with the appropriate tomato varieties as the male parent to breed tomato hybrids against TMV. In the study, the method of regression analysis was used and the genetic parameters such as combining ability and heritability were estimated. The results showed that “Dwarf yellow” has a high combining ability, especially in early yield and total yield, and is an excellent hybrid parent. The hybrid combinations were compared and evaluated. Three combinations of Dwarf Yellow × Zao Fen 2, Dianhuang × Ninghong 2 and Dianhuang × Hanks were selected.
