Genetic Diversity, Correlation and Path Analysis for Yield and Yield Components of Pea (Pisum sativum L.)

Forty six pea genotypes were evaluated for thirteen morphological characters during Rabi season, 2010 at Sher-e-Bangla Agricultural University, Dhaka, Bangladesh. Analysis of variance (ANOVA) test revealed significant differences among the genotypes for all the traits. Days to first flowering, plant height, branches plant , pod length, hundred seed weight, pods plant , seeds plant and seed yield plant exhibited that they 1 1 1 1 were controlled by additive gene action and selection for the improvement of these traits would be rewarding. The phenotypic variance was higher than the corresponding genotypic variance for all the characters. All the characters showed moderate to low phenotypic and genotypic coefficient of variation. Genotypic coefficient of variation was the highest for hundred seed weight (37.24) followed by number of branches plant (15.96) 1 and seeds plant (15.27). Hundred seed weight had the highest heritability (95.97). Pod length, hundred seed 1 weight, pods plant and seeds plant showed significant positive genotypic and phenotypic correlation with 1 1 seed yield. In path analysis, plant height, internode length, hundred seed weight, number of seeds pod and 1 seedsplant showed positive direct effect on yield. Considering genetic variability, correlation and path 1 analysis, emphasis should be given on pod length, seeds pod , seeds plant and hundred seed weight during 1 1 breeding program to improve seed yield of pea.
