چکیده
Heterosis and combining ability are two important considerations in the utilization of heterosis, which can be used to generate excellent hybrid resource candidates is very conventional breeding. In this study, ability, heritability, heterosis eight major agronomic traits were analyzed 10 tomato parents 45 crosses between them. As well as TY-301, a recognized official variety that currently selling on market was control conduct analysis, with goal selecting ideal high new hybrids commodity value, yield, early maturity, quality. The results showed both additive nonadditive genetic effects involved expression effect dominant trait inheritance. Although general (GCA) specific (SCA) not correlated, strength depends SCA, sum parental GCA values (GCAsum) did predict for some higher predictive accuracy than SCA. Compared GCAsum better performance. Finally, parent 17,969 breeding material best comprehensive performance, especially yield. We screened high-yielding candidate combination 17,927 × precocious good taste 17,666 17,927. This information may play an role selection superior combinations based analysis.
