Description A breeding programme was developed from an initial S. lycopersicum × S. lycopersicum (H 88-78-1) cross. The objective of this study was to determine the inheritance of resistant to leaf curl virus and yielding capacity in four crosses made within and between gene pools (TLBR 3 × H 88-78-1, PKM 1 × H 88-78-1, FLA 7421 × H 88-78-1 and Vaibhaw × H 88-78-1) using generation means analysis with five generations (P1, P2, F1, F2 and F3) of each population under two environment (field and glasshouse). Results showed that the character of plants and fruits morphology was fit on 1:2:1 (P1: intermediate: P2) and ToLCV (PDI) value was fit on 3:1 (resistant: susceptible) Mendalian ratio in each four F2 populations. In the present study, it was concluded that the generation mean analysis showed monogenic and partial recessiveness and incomplete penetrance. Each population displayed the additive and dominant gene action according to their heritability for using characters. The partial resistance derived from H 88-78-1 will be useful in homozygosis or may be combined with other resistance genes from other sources and can be grown in any climate challenging area.
