Abstract

The present investigation was conducted on genetic diversification, character connections, and their direct and indirect effects using 21 sweet pepper genotypes to identify superiors owing to developing variety (es) and/or utilizing the pertinent genotypes in the hybridization program. It was found that, except fruit length (FL), all of the features had larger phenotypic coefficients of variation (PCV) than genotypic variation coefficients of variation (GCV), and the gap between PCV and GCV was rather small. Except for FL (24.98%) and seed number per fruit (24.76%), all traits had a high estimation of broad sense heritability of more than 75.00%, indicating significant improvement is possible by employing standard selection procedures. High genetic advance as a percentage of the mean was observed for all the characters. Genotypic and phenotypic correlation analyses showed that there was a strong positive correlation between fruit yield per plant with fruit yield/plot and yield (t/ha) (r = 1.00**). In addition, the importance and close correlation of characters to enhance yield or to use as selection catalogues were demonstrated by the fact that the genotypic direct impacts utilized by the yield component traits were fairly bigger than their equivalent phenotypic effects.

Key words: Correlation, Direct and indirect impacts, Genetic diversification, Phenotypic and Genotypic coefficients of variation.
