Environment×Combining Ability Interaction for Quality Traits in Tomato (Solanum lycopersicum L.)

The multilocational studies were conducted to evaluate 21 hybrids of tomato in Pratapgarh(Uttar Pradesh), Varanasi (Uttar Pradesh) and Burdwan (West Bengal), India during August–February 2015–16 2016–17. Data on four quality traits viz., total soluble solids, titrable acidity, carotene content lycopene estimated. Combined analysis variance (ANOVA) revealed significant effects locations, genotypes, genotype-location interaction parents vs hybrids-location for all the traits. significance combining ability (general specific ability) their with location environmental influences Present study indicated higher estimates , lower heritability GCA/SCA ratio traitsandthereby implied preponderance non-additive gene action determination studied. Desirable parental lines identified different like EC 620438 BS 24-2 TSS, Superbug Columbia, content, H 86 620541 content. Similarly, desirable combiners identified. hybrid combination 620438×BS appeared good combiner lines/hybrids present will be useful identifying adapted a range environments.
