Analysis of genetic variability, heritability, correlation, path analysis, principal component and cluster analysis was carried for 25 blackgram genotypes grown in the foothills of Manipur. The results showed that phenotypic coefficients of variability recorded were higher than the genotypic coefficients of variability, irrespective of traits, demonstrating the effect of environment thereon. The present study revealed that the heritability (bs) estimates were maximum (>50%) for the traits such as days taken to attain the 50% flowering, number of clusters/plant, number of pods/plant and 100 seed weight. The correlation and path analysis proved the selection of the yield attributes in blackgram based on the characters, viz., number of pods/plant and number of cluster/plants. The first three principal components, having the Eigen values more than 1, contributed 84.52% towards variability among the 25 genotypes screened for quantitative traits. Based on the average linkage, 25 genotypes were grouped into five (5) clusters.

<p>Eggplants (Solanum melongena L.) are consumed worldwide in a variety of colors, shapes and sizes, thus vegetable plant breeders place great interest in developing high yielding genotypes in response to the population growth and the need to increase vegetable production. This research was aimed to determine the proper character as selection character for breeding high yielding eggplants by using estimated heritability value, coefficient of genetic diversity, characters correlation and path analysis. The experiment was conducted during 2014 to August 2015 at Cikabayan Experimental Field, Tajur Experimental Field and Pasir Sarongge Experimental Field, IPB, West Java. A total of 12 characters was observed in the 25 genotypes. Eleven characters has a high estimated heritability value and high coefficient of genetic diversity value. Those characters were time of flowering, time of harvest, fruit length, fruit weight, fruit diameter, plant height, stem length, fruit apical scar length, calyx length, the number of fruits per plant and fruit weight per plant. Results of correlation and path analysis showed that fruit length, fruit weight, fruit diameter, stem diameter, calyx length and number of fruits per plant have a direct positive effect on fruit weight per plant. Fruit weight, fruit diameter and number of fruits per plant are suitable characters in determining the selection criteria for developing high productivity eggplant.<br /><br />Keywords: path analysis, correlation, heritability, genetic diversity coefficient<br /><br /><br /></p>
