INTRODUCTION Brinjal (Solanum melongena L.) is native of India and belonging to family Solanaceae, is one of the most popularly grown in India and other parts of the world. Solanum is a very large genus and among the 22 Indian species of brinjal all are diploid with somatic chromosome number 2n = 2x = 24. It is highly productive and usually referred as the poor man’s crop. Basically, it is self pollinated crop but cross pollination also reported as high as 29 per cent due to heterostyly condition and hence it is called as often-cross pollinated or facultative-cross pollinated crop. Greater the variability in a population, more will be chance for effective selection for desirable types (Vavilov, 1951). Evaluation of the brinjal genotypes is necessary to know the performance in terms of yield and for the future selection of genotypes. The genotypes selected are released as a variety or further it can be used in breeding programme. MATERIAL AND METHODS The present investigation was carried in COH, Venkataramannagudem, Dr. Y.S.R. Horticultural University, West Godavari (A.P) during kharif 2019-20. The experiment consists of seven F2 brinjal progenies viz., Babajipet-1 × EC-169084, Tuni local × EC-169089, EC-169084 × Bhagyamati, EC-169089 × Pennada, Babajipet-1 × Babajipet-2, EC 169084 × Pennada and Babajipet-2 × EC-169084. The present investigation was carried out with the objective of selecting superior genotypes for economically important traits and to assess the effectiveness of selection by estimating per cent genetic gain and to study the effect of selection on other genetic parameters. Parameters of variability and Heritability can be calculated using formulae specified by Burton and Devane (1953) and Allard (1960). The genetic advance was calculated by formulae given by Allard (1960) and the GAM calculated using the formulae given by Johnson et al. (1955). RESULTS AND DISCUSSION Among various variability parameters, high PCV and GCV were observed in traits Number of flowers per inflorescence, Number of fruits per cluster and Fruit length to fruit girth ratio indicating that more variations and resulted good scope for crop improvement by selection. Similar results were observed Divya Arti and Sharma (2018) for Number of flowers per inflorescence, Number of fruits per cluster and Fruit length to fruit girth ratio in brinjal. Moderate PCV and GCV were found in traits Number of primary branches, Fruit girth(cm) and fruit weight. These finding are similar to Balas et al. (2019) for Number of primary branches, fruit girth in brinjal. Whereas, low PCV and GCV were recorded in plant height, days to first harvesting, number of seeds per fruit and test weight of seed. These results were in conformity with Balas et al. (2019) for days to first harvesting, number of seeds for fruit in brinjal, Priyanka et al. (2018) for test weight of seed in brinjal. All the parameters exhibited high level of heritability (88.50% to 99.87%). High level of heritability for various traits indicates that vast proportion of phenotypic variance was aspect to genotypic variance and therefore, selection could be made in this traits on the measure of phenotypic expression. These results were in conformity with Jyothi et al. (2019) for plant height, days to first harvesting, number of seeds per fruit and test weight of seed in brinjal. Balas et al. (2018); Divya Arti and Sharma (2018) for number of fruits per cluster and Ramesh et al. (2013) for fruit length to fruit girth ratio. The high heritability coupled with high GA was found for fruit weight and number of seeds per fruit indicating that these traits were controlled predominantly by additive gene effect. Therefore, phenotypic selection will be useful to improve these traits in future according to Prasad et al. (2004). High heritability along with greater GAM was found for Number of flowers per inflorescence, Number of fruits per cluster, fruit weight and fruit girth, indicates that these traits were also controlled by additive gene and selection might be useful for further improvement. These findings were in accordance with Divya Arti and Sharma (2018) for Number of flowers per inflorescence, Number of fruits per cluster, fruit weight in brinjal. The cross EC-169084 × Bhagyamati cross also recorded the highest Number of flowers per inflorescence, number of fruits per cluster, The cross Tuni local × EC-169089 recorded the highest average fruit weight and moderate value for number of fruits per cluster and days to first harvest in F2 generation.
