The investigation was conducted during the period 2016-2018 at the Institute of Forage Crops - Pleven in order to evaluate five breeding lines (№115, №29, №9А, №8, №11) and two varieties (Crystal, Kerpo) of spring forage peas. For the study period, high values of the variation coefficient were found for the traits of pods number (24.23%) and seeds number per plant (25.08%), medium ones – for plant height (17.75%), 1st pod height (13.95%), weight of 1000 seeds (13.57%) and seeds weight per plant (11.77%), and low – for seeds number in a pod (8.70%). Line №29 was of breeding interest in the grain direction. It was characterized by average height (74 cm), short vegetation period (78-90 days), and exceeds the control varieties in terms of weight of 1000 seeds (209.88 g) and seed productivity (4.88 g). The varieties Crystal and Kerpo were distinguished by good characteristics of the structural elements and can be used as parental components in the combination selection in the development of new forms in the grain direction.
