The present investigation on study of Correlation and path analysis study in chilli (Capsicum annuum L.) genotypes was carried out during during rabi crop are that sown in winter season, in the year 2016-17. The study was under taken on 30 genotypes of chilli using randomized block design (RBD) with three replication. The result on phenotypic and genotypic correlation coefficient revealed that fresh fruit yield per plant was significantly and positively correlated with total number of fruits per plant, fruit diameter, fruit pedicel length, fresh fruit weight, dry fruit weight, seed content, ascorbic acid content, oleoresin content, capsanthin content and capsaicin content. However anthracnose resistance, number of primary branches per plant, number of flowers per axil and fruit length showed significantly and negatively correlated with Fresh fruit yield per plant. The path coefficient analysis different yield and yield contributing traits on fruit diameter, length of fruit, fruits per plant and fresh weight of fruit exhibited positive direct effects on Fresh fruit yield per plant these characters play a major role in recombination breeding and suggested that direct selection based on these traits will be rewarded for crop improvement of chilli.

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.
