According to the majority of modern botanical classifications, red-yellow, tawny or, simply, wild pea (Pisum fulvum) is regarded as another of the two species in the genus Pisum, along with Pisum sativum, common pea. Recently, this species is generally considered a source of the resistance to pea weevil (Bruchus pisorum), the most important pest in pea in many regions with arid climate. Within the Annual Forage Legumes Collection (AFLCNS) of the Institute of Field and Vegetable Crops in Novi Sad, there are 15 accessions of red-yellow pea of diverse geographic origin. All of them have been included in the evaluation of the most important agronomic characteristics, mostly because of the need for a better understanding of the relationship between yield components in this species and its hybrid progenies with common pea. A small-plot trial was carried out on a chernozem soil at the Experiment Field of the Institute of Field and Vegetable Crops at Rimski Sancevi during 2005, 2006 and 2007. The trial included twelve red-yellow pea accessions from AFLCNS. There were monitored plant height (cm), first fertile node height (cm), number of nodes (/plant), ordinal number of first fertile node, number of stems (/plant), number of pods (/plant), number of seeds (/plant), thousand seeds mass (g), seed yield (g/plant), harvest index and plant mass (g). The highest seed yield was in the accessions 868277 (2.44 g/plant). Seed yield per plant was in the highest positive simple correlations with number of seeds per plant (r = 0.937) and number of pods per plant (r = 0.882).
