| dc.description.abstract | ABSTRACT The present study entitled “Genetic analysis of yield and contributing traits in tomato (Solanum lycopersicum L.)” was carried out at the Experimental Farm, Regional Horticulture Research and Training Station, Bajaura, Kullu (HP) in summer of 2019, 2020 and 2021. The experiment was laid out in Randomized Complete Block Design with three replications comprising forty six genotypes to elucidate the information on the extent of mean performance, heterosis, combining ability, nature and magnitude of gene action for different horticultural traits. Inheritance of mature fruit colour in tomato was also studied by observing the segregation pattern of different generations (F2, B1 and B2) using chi- square analysis. The analysis of variance indicated highly significant differences among all the genotypes for all the traits studied. Based on GCA effects, the parents viz., Solan Lalima and BajT-4 were the most promising for fruit yield per plant. Gene action studies indicated predominance for non additive gene action for almost all the traits except for average fruit weight. The experimental results revealed that that on the basis of overall mean Solan Lalima × BajT-4, Solan Lalima × BajT-11, Arka Meghali × BajT-10, Arka Abha × H-7998, Arka Abha × BT-21, Solan Lalima × Arka Meghali and H-7998 × BajT-4 performed well for majority of yield and yield contributing traits and these hybrids can be recommended for cultivation after multilocational testing. Chi-square analysis revealed that Solan Lalima (red) × BN-7 (yellow) showed dominance of red colour over yellow colour. | en_US |
