Abstract
Fifty seven genotypes were evaluated for yield and yield attributing characters at farmers field, Mittachinthavaripalle, Punganur, Chittoor District, Andhra Pradesh during Summer, 2023. The experiment was laid out in Randomized Block Design along with three replications. High GCV and PCV were recorded for number of fruits per plant, fruit weight, yield per plant, fruit length, pericarp thickness, fruit width, titrable acidity, plant height and ascorbic acid. This indicates the existence of wider genetic variability, which would be amenable for further selection. Low estimates of genotypic and phenotypic coefficient of variations were observed for days to 50% flowering, number of primary branches and lycopene suggesting the narrow range of genetic variability for these traits. High heritability coupled with high genetic advance over mean were observed for plant height, days to 50% flowering, number of fruits per plant, fruit weight, fruit length, fruit width, pericarp thickness, total soluble solids, lycopene, ascorbic acid, titrable acidity and yield per plant which shown high level of genetic advance indicating opportunity for better selection response. The results of genetic parameters from the present study may helpful to the plant breeder in selection of elite genotypes from diverse genetic populations.
