Genetic variability for growth and yield traits in tomato (Lycopersicon esculentum)

Nisha Kataria, Simranpreet Kaur, Khushveer Singh and Navdeep Singh

The present study Genetic Variability for growth and yield traits in Tomato was carried out to investigate yield and quality traits in tomato, in order to generate information regarding the extent of genetic variability, heritability and genetic gain. The experiment conducted on January, 2024 in two row spacing of 45 cm, All rows on which transplanting were done on raised bed to facilitate irrigation and other cultural operation. The treatments were planted in Randomized Block Design with three replications. Observations were recorded on twelve quantitative characters of tomato and these recorded data utilized for estimation of genotypic and phenotypic coefficient of variation, heritability in broad sense, genetic advance, genetic advance in percent of mean, genotypic and phenotypic correlation coefficients and genetic divergence. The analysis of variance of the experiment indicated highly significant differences among twelve genotypes of germplasm collection for all the characters studied. Average fruit weight, number of fruits per plant, locules per fruit, number of primary branches per plant, and total fruit output per plant all showed high heritability combined with high genetic progress, suggesting a strong selection response, these features would be beneficial for increasing tomato productivity since polar and equatorial fruit diameter, average fruit weight, and TSS have a positive, substantial, and favorable correlation with total fruit yield. High magnitude of phenotypic coefficients of variation was observed in case of total fruit yield per plant followed by equatorial diameter of fruit, average fruit weight, plant height, number of primary branches per plant, p Rick.

Substantial positive indirect effect via average fruit weight, equatorial diameter of fruit, polar diameter of fruit, number of primary branches per plant, days to first fruit harvest, plant height were exerted by total fruit yield per plant on average fruit yield per plant. Genetic parameters in association with correlation study indicated that for selection of superior genotypes primary emphasis should be given on fruit yield per plant and average fruit weight.
