Bulgarian Journal of Agricultural Science, 16(2), 203-211.1310-0351http://hdl.handle.net/11452/25346This study was carried out to determine simple correlations between seed yield and certain important agronomical characters and direct and indirect effects of these characters on seed yield in field bean. The research was conducted with 30 bean cultivars or lines under Isparta ecological conditions in 1996 and 1997. Seed yield, number of branches per plant, number of pods per plant, number of seeds per pod, number of seeds per plant, number of immature pods per plant, biomass yield, seed yield per plant, 1000 seed weight, pod lenght, pod width, plant height and first pod height were observed in the study. According to the results, simple correlation coefficients were positively significant in all pairs of the characters except correlations between seed yield per hectare and pod lenght, pod width and first pod height. The highest positive correlations were observed between seed yield per plant with biomass yield (r= +0.974**), number of pods per plant (r =0.860**) and number of branches per plant (r =+790**). Path coefficient analysis indicated that seed yield per plant had the greatest direct effect (+0.668) on seed yield per hectare, followed by 1000 seed weight (+0.185) and plant height (+0.301). Percentages of direct effects on seed yield per hectare were 63.1%, 51.7% and 48.9%, respectively, for seed yield per plant, 1000 seed weight and plant height. In the study, characters such as number of pods per plant, biomass yield, number of branches per plant, number of seeds per plant, number of immature pods per plant, number of seeds per pod and plant height gave the highest indirect effects on seed yield per hectare through seed yield per plant (with contributions 63.6%, 63.0%, 62.8%, 58.1%, 47.8%, 42.3%, and 33.6% respectively).eninfo:eu-repo/semantics/openAccessPhaseolus vulgarisAgronomical charactersCorrelation coefficientPath analysisYieild componentEnvironmental sciences & ecologyPhaseolus vulgarisArticle0002802218000102-s2.0-77956441374203211162Environmental sciencesCicer; Genetic Advances; Harvest Index
