【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。更多还原

【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.h~2_N of fruit number per truss and fruit width were higher,so that they should be selected in earlier generations,while h~2_N of per fruit mass and plot yield were lower,so they should be selected in the later generations.Per fruit mass was the most important factor about plot yield,and it has a significant negative correlation with per truss fruit number.更多还原
