Frequency distribution and genetic variability for yield attributing traits in F₂ population of Tomato Cross, IIHR-2373 X  Arka Alok

The F₂ population of the cross IIHR-2373 X Arka Alok's genetic parameters were examined in order to clarify the frequency distribution, genetic variability, heritability, and genetic advancement of tomatoes (Solanum lycopersicum L.). The results of the variability study demonstrated that all of the characteristics assessed in the segregating population had a reasonable degree of arbitrariness. Except for pH, ascorbic acid, number of locules, days to first flowering, and pulp content, which displayed negative skewness and platykurtic distribution, the frequency distribution of the F₂ population demonstrated positive skewness with platykurtic distribution for all traits. Except for the number of fruits per cluster and the days to first flowering, minimal variation was found between the phenotypic coefficient of variation (PCV) and genotypic coefficient of variation (GCV) for all characters. This suggests that environmental factors less influenced most traits for their phenotypic expression. Except for fruit diameter, days to first flowering, and quantity of fruits per cluster, all attributes showed strong heritability combined with high genetic advancement as a percent mean, suggesting a substantial opportunity for improvement through selection for most of these traits. To effectively choose a superior genotype of tomato through breeding, a breeding strategy must first investigate genetic diversity in the available germplasm.
