The discovery of recessive gene af controlling the transformation of all leaflets into tendrils (afila) in field pea is often considered the most important event in the field pea breeding. Such cultivars are characterized by a significantly improved standing ability, non-decreased photosynthetic activity and often higher grain yields in comparison to the cultivars with normal leaf type. A small plot trial has been carried out at the Experiment Field of the Institute of Field and Vegetables Crops at Rimski Sancevi (Serbia), between 2006 and 2008, including 12 afila lines of field pea. The study included plant height (cm), number of nodes per plant, number of fertile nodes per plant, number of pods per plant, number of grains per plant, thousand grains mass (g) and grain yield per plant. The average grain yield per plant varied from 2.15 g in the line AF09 to 7.78g in the line AF02. Grain yield per plant was in the highest positive simple correlation with number of pods per plant (r = 0.951). Thousand grains mass was the only grain yield component that was in negative simple correlations with all other grain yield components, most notably with number of nodes per plant (r = -0.668).
