Abstract:
Field pea (Pisum sativum L.) is among the major food crops grown globally for its high protein content. However there is no detailed nutrient composition profile and recently challenged with a storage pest, Callosobruchus chinensis L. This study was carried out to know the nutrient composition and quantify the damage caused by the pest and identify the sources of resistance in the genotypes in Ethiopia. The study was conducted at Kulumsa Agricultural Research Center (KARC) in Ethiopia, during 2019. Nutrients were estimated in laboratory analysis and callosobruchus chinensis L. was used to challenge 26 field pea genotypes under no choice condition, in the laboratory. Results showed a significant differences (p10) (Table 4). Genotypes; fpcoll-1/07, fpcoll-2/07, fpcoll-28/07, fpcoll-29/07, fpcoll-30/07, fpcoll-31/07, fpcoll-40/07, fpcoll-41/07, fpcoll-42/07/ had high values (ppm) for; ca, k, mg, and zn, whereas all improved, introduced crossed line of considered field peal genotypes had low values (ppm) for the above nutrients. In general there is a possibility that promising field pea genotypes in both high nutrient composition and less susceptibility could be used in a future breeding system.
