Studies on Variability, Heritability and Genetic Advance for Yield and Its Attributes in Brinjal (Solanum melongena L.)

The present investigation carried out on “variability, heritability and genetic advance analysis in relation to selection of parental lines in brinjal (Solanum melongena L.)” at Horticultural Research Centre of Sardar Vallabhbhai Patel University of Agriculture and Technology, Meerut. The experimental material comprised of eight parental lines namely, K.S-331, DBL-24, A. Abhilomb, A. Parthibha, J.B.-6, F.Collection-2, J.B.L.-03-04 and Assury along with twenty eight F1crosses which were produced by the parents. These parental lines were collect from IIVR Varanasi and used for further crossing programme in half diallel crosses fashion. Parental lines were grown during Kharif 2017 and all possible cross combinations were made to produce 28 F1s. 12 different characters like Plant height (cm), primary branches per plant, plant spread, days to first flowering, days to first fruit set, days to first fruit picking, average fruit weight, fruit length, fruit diameter, fruit index, fruits per plant and yield per plant were taken into consideration. Analysis of variance in the present investigation shows that the crosses evaluated differed significantly among all the 28 traits. The results revealed that among the all cross A. Parthibha x A. Abhilomb produced highest fruit yield, plant height, fruit weight and also took minimum days to flowering and days to fruit set. High heritability in broad sense was observed for average fruit weight, high genetic advance in percent of mean was observed for diameter of fruit followed by average fruit weight. High genotypic coefficient of variation (GCV) was recorded for diameter of fruit followed by fruit index and phenotypic coefficient of variation (PCV) for diameter of fruit followed by average fruit weight.
