Abstract: Collection of diverse germplasm and their systematic evaluation assume considerable importance in any crop improvement programme. In the present experiment nineteen genotypes of brinjal (Solanum melongena L.) comprising local collections and established varieties were evaluated with the objective of estimating different genetic parameters and genetic associations of yield and yield attributing traits. The experiment was conducted at the Experimental Farm, Department of Horticulture, Assam Agricultural University, Jorhat during the period from October 2009 to March 2010 following Randomized Block Design with three replications. Analyses of variance revealed substantial variations among the genotypes for the traits under study. The genotype GB-09-05 was the superior performer for yield (1.38 kg/plant), fruit weight (356.0 g) and plant spread (122.33 cm). Some other promising genotypes were JB-3, GB 09-02-02 and GB-09/10-14. Performance of local brinjal genotypes was better than established varieties. Estimation of genetic parameters indicated high GCV (77.95%) and PCV (78.22%) for fruit-length/diameter ratio. High heritability values of more than 90% were observed for fruit weight (99.55%), fruit-length/diameter ratio (99.17%), plant spread (98.14%), fruit length (97.37%), plant height (96.93%) and number of fruits/plant (96.79%). Expected genetic advance as per cent of mean was highest (89.53%) for number of fruits per plant. Fruit yield per plant was significantly and positively correlated with fruit weight, leaf length, leaf width, plant height and plant spread. Fruit weight was significantly and negatively correlated to number of fruits/plant. From the overall performance of genotypes, it is revealed that promising genotypes were GB-09-05, JB-3, GB 09-02-02 and GB-09/10-14 which can be selected directly or utilized in future breeding programmes.
