The majority of modern botanical classifications classify Ethiopian pea within the species Pisum sativum and gives it the rank of subspecies, that is, Pisum sativum subsp. abyssinicum Govorov. On the other hand, some research reveals a possibility that it may be considered a separate species that is the third within the genus. Ethiopian pea is, in a similar way to other wild pea taxa, often a source to important diseases. Within the Annual Forage Legumes Collection (AFLCNS) of the Institute of Field and Vegetable Crops in Novi Sad, there are 15 accessions of Ethiopian pea of diverse geographic origin. All of them have been included in the evaluation of the most important agronomic characteristics, in order to get a better comprehension of the relationship between forage and seed yield components in both this species and its hybrid progenies with common pea and its subtaxa. 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 MG 101785 (5.33 g/plant). Seed yield per plant was in the highest positive simple correlations with number of seeds per plant (r = 0.877) and number of pods per plant (r = 0.708).
