Abstract

In Ethiopia, field pea (Pisum sativum L.) is the main source of protein for resource poor growers. The improvement of varieties for yield and disease resistance is one of the important activities to support farmers and improve the productivity of the crop. Consequently, this study was showed to evaluate the genotypic correlations, phenotypic correlations and path coefficient analysis between the field pea genotypes for yield and yield associated traits. Forty-nine field pea genotypes were evaluated in simple lattice design at two locations Bekoji and Asasa in 2018/2019 cropping time of year. Grain yield per plot had positive and highly significant genotypic association through plant height whereas highly significant phenotypic correlation observed between grain yield and plant height and biomass yield. At Bekoji genotypic path analysis, days to 50% flowering, plant height, grain filling period, thousand seed weight, harvest index and total biomass showed strong positive direct effect on grain yield per plot. At Asasa the path analysis for grain yield at genotypic level showed that harvest index, thousand seed weight, plant height, days to 50% flowering and days to 95% physiological maturity and total biomass yield exerted positive direct effect on grain yield per plot. Path coefficient analysis at genotypic levels of the combined data exhibited that days to 50% flowering and total biomass per plot had strong positive direct effect on grain yield per plot. The phenotypic path analysis of the combined data revealed total biomass yield, thousand seed weight, plant height and days to maturity has strong positive direct effect on grain yield per plot. The study showed the existence of reasonable genetic variability between the field pea genotypes that can be exploited in breeding programs.
