Sažetak
Knowing combining ability of parental lines is important in estimating a potential of a parent in a new variety creation. The general opinion is that parents with good combining ability will give a good new genotype. F1 generations with high values of desired traits often have high probability of giving more valuable progeny in later generations. Aim of this research is to estimate general combining ability of 6 parental lines of field pea based on 6×6 diallel cross without reciprocal crosses. General combining ability of each parent was calculated as an average value of progeny of all parental combinations containing respective parent. There were tested 15 F1 combinations of progeny of diallel cross on traits of plant height and grain yield per plant in 2008 year. Parental lines were spring field pea varieties as follows: Danish yellow dry pea Anno, medium tall (about 52 cm) with afila leaf type, Croatian yellow dry pea Gold with low plant habit (about 48 cm tall) and afila leaf type, American yellow dry pea Shawnee with high plant habit (about 84 cm tall) and wild leaf type, American green dry pea Joel with high plant habit (about 83 cm tall) and wild leaf type, new yellow dry pea genotype PF-G1, creation of Faculty of Agriculture in Osijek and Agricultural Institute Osijek, with medium high plant habit (about 65 cm tall) and wild leaf type and Serbian field pea NS-Junior, arvense type for fodder and grain (yellow grain) production with high plant habit (about 118 cm tall) and wild leaf type. F1 progenies were seeded in optimal agrotechnical term (12th March 2008) with stand of about 100 seeds per square meter in microplots, in Osijek, on eutric cambisol. Upon harvest, there were determined plant height and grain yield per plant. The general combining ability of each parent for the plant height trait was as follows: Gold 66, 06 cm, Anno 66, 41cm, PF-G1 78, 66cm, Shawnee 87, 60cm, Joel 88, 91cm and NS-Junior 96, 34 cm. For the grain yield per plant the general combining ability was as follows: Gold 6, 64 g, Shawnee 7, 00 g, Anno 7, 26 g, Joel 7.51 g, PF-G1 7, 71 g and NS-Junior 7, 95 g. NS-Junior has performed the best combining ability for grain yield per plant and high plant height. However, association of high yield with high plant height is considered as unfavorable in grain production due to plant lodging potential and excessive biomass that impedes harvesting. If in segregating generations the NS-Junior's progeny fail to segregate separately regarding these traits, the best genotypes will probably be obtained of other good combinators.
