dc.description.abstractTwenty nine Byadgi Dabbi chilli accessions were evaluated in randomized complete block design with two replications to study the variability, correlation, path and divergence studies at Horticultural Research and Extension Centre, Devihosur (Haveri). Analysis of variance revealed that highly significant difference among accessions for all the traits studied. Very high GCV and PCV were observed for number of fruits per plant, dry fruit yield per plant, yield per plot, yield per hectare and capsaicin content. Very high heritability coupled with very high GAM were recorded for number of fruits per plant, dry fruit yield per plant, yield per plot, yield per hectare, weight of 100 dry fruits, number of seeds per fruit and capsaicin content indicating the predominance of additive gene action, hence direct phenotypic selection is useful with respect to these traits. Yield per plant was positively and significantly associated with plant height at 120 DAT, plant spread (E-W) at 120 DAT, plant spread (N-S) at 120 DAT, secondary branches, days to first flowering, number of fruits per plant and average fruit weight at both genotypic and phenotypic level. Path analysis revealed that plant height at 120 DAT, plant spread (N-S) at 120 DAT, secondary branches and number of fruits per plant had high positive direct effects on dry fruit yield per plant. By following Mahalanobis D2 analysis, 29 accessions of chilli were grouped into 6 clusters. The cluster III showed maximum intra-cluster distance and the maximum inter- cluster distance was observed between cluster I and VI. Capsaicin contributed maximum to the total diversity. The highest cluster mean for fruit yield per plant was observed in cluster III. Maximum divergence was observed between these clusters. Hence the crosses between accessions of these clusters may be tried for improvement of yield. The high yielding DKK-G-3, DKS-DD-2, DKS-ND-2 and DKHBD-1 can be further assessed for stability before exploiting them for future use.en_US
