Studies on heterosis in brinjal for yield and yield components

Abstract

The present investigation entitled “Genetic analysis of F1 hybrids in brinjal” was undertaken during kharif and summer season of 2014-15 at Department of Horticulture, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola with the objective to estimate the heterosis for yield and its component traits. Eleven geographical and genetically diverced parents of various economic traits (four lines and seven testers) were crossed in line x tester mating design to obtain 28 F1s. These crosses, parents and check were grown in kharif and summer season of 2014-15 in randomized block design with three replications. The per se performance for yield characters, among the eleven parents Bhatai Local, Wadsa Local, Aruna, Ruchira, Chandur Local and White Brinjal have found superior in performance, while among the twenty eight crosses, Wadsa Local x Ruchira, Wadsa Local x Chandur Local, Wadsa Local x DBSR-52, Aruna x Ruchira, Aruna x Chandur Local, Aruna x DBSR-52, Bahtai Local x Ruchira and Bhatai Local x Chandur Local have found superior in performance. On the basis of magnitude of standard heterosis, the crosses Wadsa Local x Ruchira, Wadsa Local x Chandur Local, Wadsa Local x DBSR-52, Aruna x Ruchira, Aruna x Chandur Local, Aruna x DBSR-52, Bahtai Local x Ruchira and Bhatai Local x Chandur Local have found superior performance over other crosses in study.
