dc.description.abstractThe present investigation entitled “Heterosis and combining ability analysis in relation to selection of parental lines in brinjal (Solanum melongena L.)’’was undertaken to collect information on genetic parameters for yield and its components from a eight parents in a half diallel mating design in brinjal at Horticulture Research Centre, Sardar Vallabhbhai Patel University of Agriculture & Technology, Meerut (U.P.) during Kharif,2016-17 and 2017-18. The experimental material was comprised of eight diverse parents and their 28 F1s. All genotypes were evaluated in a complete randomized block design with three replications. The data were recorded on twelve characters plant height (cm), primary branches per plant, plant spread (cm), days to first flowering, days to first fruit set, days to first fruit picking, average fruit weight (gm), length of fruit (cm), diameter of fruit(cm), fruit index, fruits per plant and yield per plant (g.). The data were recorded subjected to various statistical analyses. Analysis of variance observed highly significant differences among the parents and F1s for all the characters. It is logical to suggest the appropriate breeding methodology on the basis of genetic information gathered from the present studies in brinjal which allowed maximum exploitation of both additive and non additive components with gene action. Suggestions are advocated for consideration during formulation of breeding programme in brinjal on the basis of result obtained in the present investigation for fruit yield and its components governed by additive and non additive gene. There for progeny and recurrent selection may be recommended or improvement in fruit yield and its components in brinjal. The higher proportion of specific combining ability variance highly significant dominance and over dominance components for yield and its contributing traits would be helpful in commercial exploitation of hybrids in brinjal. Some crosses A. Parthibha x A. Abhilomb, JB-6 x DBL-24, F.Collection-2 x A. Abhilomb, F. Collection-2 x A. Parthibha (C.K.) were found good combination for further development and for further breeding program in brinjal. First two crosses (hybrids) recommended for commercial cultivation at the farmers field.en_US
