Abstract: Brinjal or eggplant is an important vegetable crop of Indian origin having wide variability with respect to different qualitative characters. In India, it is one of the most common, popular vegetable crops grown throughout the country. Being a centre of origin, eggplant has a huge genetic variability in the country, which offers much scope for improvement through heterosis breeding. The efforts could enhance its quality and productivity without scarifying the consumer’s choice. The combining ability is also one of the important genetic tools, which provide a guideline for an assessment of the relative breeding potential of the parents or identifying the best combiners, which may be hybridized either to exploit heterosis or to accumulate fixable genes. The knowledge regarding the nature of gene action is essential for choosing suitable breeding methodologies for brinjal improvement. The present research work is conducted to exploit the nature of gene action for various fruit yield attributing traits. The hybrids has shown significant differences for all the characters except for plant height. The effects of hybrids were partitioned into lines, testers and their interactions. The lines were significant for most of the characters except for the number of primary branches and plant height. Among testers, the differences were non-significant for days to first picking, number of fruits per cluster and plant height, whereas other characters were found significant. The highest sca effect was observed in JB-9 x DMU-1 (7.45) fruit weight, JB-9 x CO-11 (0.99) fruit girth, DBR - 8 x DMU - 1(3.49) fruit length, JB-9 x JKGEH-6012 (2.58) number of fruits per plant, DBR-8 x B.deoria (0.45) number of primary branches per plant and JB-9 x JKGEH-6012 (2.51) for fruit yield per plant. Gene action analysis revealed the preponderance of both additive and non-additive genes for yield and its contributing characters.
