Abstract. An analysis was carried out during 2011–2013 on eight field pea genotypes. On the basis of the obtained results, the following conclusions may be drawn and used for further research on the quantitative traits on forage pea and its application in breeding and the development of new varieties: Analysis of variance showed significant differences among genotypes for all traits. The results of coefficient of variation analysis showed that the genotypic coefficient of variation was higher than the phenotypic coefficient of variation. For all traits studied were found high heritability, indicated that these traits could be improve through selection procedure. For plant height and seeds per plant, line №115 and №9A were classified as high general adaptability to environment. The cultivars Kerpo and Kristal were classified as high general adaptability for seed weight per plant. For almost all traits line №29 was classified as having specific adaptability to unfavorable environment.
