 ABSTRACT

A study was conducted to find out the genetic variability in F2 population of cross Utkal Raja x Arka Sourabh. Higher estimates of PCV and GCV were observed for the traits like plant height, number of branches at peak harvest stage, number of clusters per plant, days to first flowering, number of fruits per plant, average fruit weight and yield per plant. For traits like TSS and total acidity the estimates of PCV and GCV were found moderate. Higher heritability coupled with high genetic advance as per cent mean were observed for plant height, number of clusters per plant, days to first flowering, number of fruits per plant, average fruit weight, yield per plant and total acidity indicates the predominance of additive gene component. Thus, there is much scope for improving these characters by simple selection in further generations.

Key words: Tomato, Variability, PCV, GCV, F2 population, Yield.
