Abstract

A study was conducted at Zifta district, Gharbia governorate, at middle delta region of Egypt during seven successive seasons of 2009-2015 to study the genetic variability and heritability for some plant and fruit characteristics in tomato. Fifteen F7 lines were selected from 4 F2 generations of six generations of selection. The estimated coefficient of variance (C.V %) values (degree of homogeneity) differed among the studied genotypes for the same character and from trait to another of the same genotype. The selected genotypes were enough homogenous for the studied traits and then it could be considered as new lines. A great diversity and significant differences were observed among the fifteen selected genotypes for all studied traits. The lines S.209, K.111-1, K.111-6, AL. 3-1-3 and EUR. 2-2 were considered the best lines for yield and fruit quality traits, and could be used in breeding programs to develop new local F1 hybrids of tomato. The results showed high values for genotypic coefficient of variation (G.C.V %) compared with the phenotypic coefficient of variation (P.C.V %) and high heritability in broad sense (h2bs) for all studied traits. The G.V.C% vs P.C.V% and (h2bs)values were 18.43 vs 22.08% and 0.70 for (days to 50% flowering), 20.09 vs 22.46 and 0.8( for plant height ),22.94 vs 24.80 and 0.86( for number of branches ),16.67 vs 17.26 and 0.93 (for early yield ), 18.25 vs 18.53 and 0.94 (for total yield ), 16.59 vs 19.22 and 0.75 ( for fruit firmness),indicating small environmental effects and large additive genetic components of the phenotypic variation for these traits and can be improved through selection programs.
