Correlation and Path Coefficient Analyses in Hot Pepper (Capsicum annum L.)

Résumé

Abstract To assess the correlation and find out the direct and indirect effect of yield attributing traits on yield, twenty six accessions and four varieties were grown during the off-season period from November 2016 to May 2017 under irrigation at Dire dawa, Ethiopia. The experiment was conducted using RCBD design with three replications. Plant height, primary branch per plot, days to fifty percent flowering, stem width, number of fruit per plant, fruit length, days to maturity and number of fruit per plant were positive and highly significantly correlated with dry fruit yield per plot at both genotypic and phenotypic correlation. Plant height (0.1081), number of fruit per plant (0.2610), fruit length (0.4293), stem width (0.4059), pedicel length (0.0122), days to maturity (0.0401) and internode length (0.0227) exerted positive direct effect on dry fruit yield per plot at phenotypic level. Genotypic path analysis showed that days to fifty percent flowering (0.0956), stem width (0.5867), fruit length (0.3671), plant height (0.0754), number of fruit per plant (0.2673) and internode length (0.0079)had positive direct effect. The direct effect of these characters on dry fruit yield per plot indicates that improvement on these traits may increase yield.
