It is estimated that the total brinjal area and production in India were0.71 million hectares and 13.5 million tonnes, respectively (Anonymous, 2014). In most of the countries, brinjal is the major component of the human diet. It is rich source of protein, P, Fe, Ca, K, Mg, Na and fibre (Nyadanu and Lowor, 2015). It has medicinal value for asthma, allergic rhinitis, constipation, skin infections, joint pains, dyspepsia and rheumatic diseases (Nwodo et al., 2011). It is impossible to have one common cultivar to suit different localities and local preferences. So, there is required to improve the yield potential by developing hybrids and its derivatives of brinjal through hybridization (Sherly, 2007). The combining ability analysis is an important tool in preferring suitable parents for hybridization and superior cross combinations through general International Journal of Current Microbiology and Applied Sciences ISSN: 2319-7706 Volume 6 Number 10 (2017) pp. 3424-3429 Journal homepage: http://www.ijcmas.com The present investigation was undertaken for combining ability studies on quantitative and qualitative traits at C.H.F., CAU, Pasighat, A.P. The 28 F 1 hybrids were developed by crossing 8 diverse brinjal genotypes/varieties in half diallel fashion. The variances due to GCA and SCA were significant for most of the characters indicating the importance of both additive and non-additive gene action in the inheritance of these characters. The highest gca effect for fruit yield was found in CHFB-6 (0.52) and Swarna Pratibha (0.44).Earliest flowering and harvesting was found in CHFB-7 x Solanum gilo with a sca value of -5.59 and -5.81, respectively. Pant Rituraj x CHFB-6 and Pant Rituraj x CHFB-7 were showed the significant response in fruit yield per plant with other characters (Plant height, number of seeds per fruit, solasodine and anthocyanin content) for sca effects. Swarna Pratibha x Pusa Purple Long was found significant sca effects for fruit yield per plant including qualitative traits. These hybrids can be used for further breeding programme regarding fruit yield, quality traits and earliness. Therefore, the current study could be evidence for hybrid breeding approaches that strengthens in improving yield, earliness together with quality traits.
