Abstract
A three-year trial (2000-2002) was aimed to investigate the grain yield of nine pea genotypes with different leaf type. One (Akatsievydnaya forma) had acacia (Aftl), four (NS-junior, Moravac, Javor and Amino) normal (AfTl) and four (Jezero, 4(1993), CD and Primeroy) afila (afTl) leaf type. Average plant height (PH), first pod height (FPH), internode number (IN), pod number per plant (PNP), grain number per plant (GNP), plant mass (PM), grain yield per plant (GYP) and per area unit (GYA), harvest index (HI) and thousand grains weight (TGW) were studied. There existed significant differences in all yield components, both between the different leaf type groups and between the genotypes of the same group. The AfTl cultivars had the greatest values for PH (75.2 cm), FPH (43.5 cm), IN (18.9), PNP (8.7), GNP (34.2), PM (15.89 g) and GYP (6.97 g). The afTl genotypes had the greatest HI (0.56), GYA (2980 t/ha) and TGW (255 g). As for the cultivars, NS-junior was characterized by the greatest values of PH (120.4 cm), FPH (68,6 cm). IN (22.2), PNP (11.3), GNP (42.5) and PM (17.95 g). Javor had the greatest GYP (8.56 g), while the greatest HI was determined in genotype 4(1993)(0,60). The greatest GYA was in Primeroy (4298 kg/ha) and the greatest TGW was measured in Moravac (301 g).
