| 摘 要： | 02S02和02S18是“串番茄”育种的好材料, 02S35 ×02S45、02S15 ×02S51是综合性状优良的组合。单花序果实个数和果实横径性状狭义遗传力较高, 在早期世代选择效果明显, 单果质量、小区产量等性状遗传力较低, 宜在高世代进行选择。相关分析表明, 单果质量是串番茄最重要的产量组成因子,单果质量与单花序果实数呈极显著的负相关关系。

| Abstract: | The results showed that 02S02 and 02S18 were good materials for truss tomato breeding.02S35 ×02S45 and 02S15 ×02S51 had better representation than other combinations. h2N of fruit number per truss and fruit width were higher, so that they should be selected in earlier generations, while h2N of per fruit mass and p lot yield were lower, so they should be selected in the later generations. Per fruitmasswas the most important factor about p lot yield, and it has a significant negative correlation with per truss fruit number. |
