| Abstract | ||
| Eight tomato genotypes (seven lines and Castle Rock cultivar) were evaluated for yield and growth characteristics. Also, their phenotypic and genotypic stabilities were determined over four environments (two locations during seasons, 2011 and 2012). Plant height, number of branches per plant, fruit length, fruit diameter, fruit flesh thickness, vitamin C, total soluble solids (T.S.S.), dry weight of fruit, weight of fruit, number of fruit per plant, early yield and total yield were studied. The results of the combined analysis of variance for the traits under study showed highly significant effects for genotypes (G),environments (E) and genotype x environment (G x E) interaction. The genotypes L-7, L-6 and L-2 were stable with higher mean compared to grand mean. | ||
