Among legumes, the field pea has multiple purpose of fixing atmospheric nitrogen andrnproviding protein. This study was undertaken to identify the phenotypic diversity of fieldrnpea (Pisum sativum L.) landrace accessions, improved and introduced varieties. It wasrnplanted in two locations namely Holeta and Debrezeit agricultural research centers usingrnRandomized Complete Block Design (RCBD) with 3 replications during the 2016-2017rncropping season. Standard morphological measurements and scores were taken and thernharvested grains were analyzed for their mineral contents including Iron, Zinc, Calcium,rnCopper, Potassium, Magnesium, Phosphorus and Selenium. The morphological andrnmineral content data were analyzed with descriptive and inferential statistics. Therngenotypes showed morphological diversity as observed in the field trails. The resultsrnshowed that significant differences exist among samples, within blocks and acrossrnlocations. Cluster analysis for average performances grouped the genotypes into tworndifferent classes where cluster 1 had short maturity period whereas cluster 2 had highrngrain production and total biomass production even though they are late maturing. In therncorrelation analysis, days to maturity was highly correlated to total biomass productionrnand grain yield to which breeders draw much attention. All the nine minerals that werernanalyzed, was there but varied from sample to sample. The amounts of Ca, K, Mg and Prnwere relatively higher in the landraces than in the other samples. It had high Ca, Fe and Prncompared to lentil and faba bean. There was strong positive correlation between thernresearch sites in Holeta and Debrezeit. Diseases like ascochyta blight and powdery mildewrnwith scales of 1-9 were present. From 77 samples RAYA 1, DEKOKO 41 and DEKOKO 15 werernresistant for both diseases. The early genotypes (the DEKOKO varieties) can be used inrndrought prone areas or in double cropping while those lines shown to be resistant tornascochyta blight and powdery mildew could be taken up in breeding programs.rnKey words: Chemical composition, correlation, cluster, morphological diversity, RCBD,rnPisum sativum
