Pea (Pisum sativum L.) is an annual plant with a high nutritional value and dietary fibers. The aim of the present study is to determine of genome size variation of some pea cultivars and ecotypes by DNA, protein, and nucleus. Tested samples demonstrated a small different value of nuclear content via flow cytometry analysis. These tested plants have verified the existence of expected ploidy levels as diploid plants. Nuclear DNA content ranged from 4.25 to 4.53. Comparison of globular protein accumulation in between pea cultivars and populations, cultivars revealed that globular protein accumulation was higher than populations samples; on the other hand, albumin protein accumulation showed a similar level for all the tested samples. Globular protein amount was between 35 kDa and 100 kDa.
