Abstract

To evaluate and classify phonological and morphological traits of 64 Common bean (Phaseolus vulgaris L.) genotypes, a triple lattice experiment was conducted at the research farm of Espiran in 2014. Each plot consisted 5 rows, 3 m length with row spacing of 30 cm and within row spacing of 12.5 cm. 24 seeds were seeded in each row. Fertilizer applications, weed control and other agricultural practices were done on 10 randomly selected plants of each plot. Factor analysis based on principal component method revealed four important factors which accounted for 74% of the total variation. The eigenvalues of these four factors were 4.42, 3.11, 1.74 and 1.17, respectively. The first factor which accounted for32% of the variation was related with days to maturity, number of primary branches, mean number of seeds/pod, seed thickness average and seed yield. This factor was regarded as yield primary factor. All variable in factor 1, unless days to maturity had positive loadings. The second factor
