The number of species in the genus Pisum L. has been far from consensus since the species in the genus have been reported as two to five or as monotypic. The aim of the present study is therefore to bring to light phylogenetic relationship on morphological traits in five pea taxa including Pisum sativum subsp. sativum var. sativum L. (garden pea) and P. sativum subsp. sativum var. arvense L. (Poir.) (field pea), P. sativum subsp. abyssinicum A. Braun (Dekoko or Abyssinian pea), P. sativum subsp. elatius M. Bieb. and P. fulvum Sib. & Sm. using multivariate cluster analysis (MCA). According to MCA analysis, P. sativum subsp. sativum var. sativum and P. sativum subsp. sativum var. arvense were clustered in the same group, whereas P. sativum subsp. abyssinicum was closer to these two taxa. Although wild species including P. sativum subsp. elatius and P. fulvum were found to be different from the cultivated species, P. fulvum was distinctly different from the other taxa. Phylogenetic relationship among taxa in the genus Pisum was clearly brought to light as the useful findings in the present study.
