The present investigation entitled “Genetic analysis of F1 hybrids in brinjal (Solanum melongena L.)” was carried out at Main Garden, Department of Horticulture, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola. Eleven genotypes (Aruna, Bhandara local, Wadsa local, Bhatai local, Manjarigota, Chandur local, Ruchira, Krishna Kathi, White Round, DBSR-52, White Brinjal) were crossed in line x tester mating design during kharif 2013. All parents and resultant crosses with standard check Phule Arjun (F1) were evaluated during Kharif and summer season of 2014-15 in Randamised Block Design with three replications. Among female parents, Bhatai local, Wadsa local, Aruna and among male parents, DBSR-52, Ruchira, Chandur local were identified as good combiner for growth, flowering (earliness), higher yield and quality characters. Six crosses viz., Bhandara local x ManjariGota, Wadsa local x Chandur local, Wadsa local x White brinjal, Wadsa local x Ruchira, Aruna x Chandur local and Bhatai local x Ruchira exhibited significant sca effects for yield per plant and yield per hectare. The crosses viz., Wadsa local x Ruchira, Wadsa local x Chandur local, Bhatai local x Ruchira and Aruna x Chandur local were identified as promising hybrids on the basis of significant sca effects and both the parents involved in these crosses had good combining ability effects for yield per plant and most of the characters studied. Additive gene action was found to be predominant for all the characters in pooled mean, except plant spread where non-additive gene action was predominant. Analysis of genetic components of variation revealed that the importance of additive gene action operating in inheritance of yield and its important components.
