A STUDY ON THE DETERMINATION OF THE PERFORMANCE OF SOME YIELD COMPONENTS IN DRY BEAN GENOTYPES (PHASEOLUS VULGARIS L.) IN DIFFERENT ENVIRONMENTS
MetadataShow full item record
This study aimed to determine the responses of dry bean genotypes to different environments in terms of yield components. The study was carried out for five years (from 2011 to 2015 year) with a total of 20 dry bean genotypes comprising 7 registered lines and 13 advanced lines. In the study, years were defined as environment. Although planting varied depending on climate conditions, all plantings during the five-year period were carried out in May. The GGE [genotype main effect (G) and genotype by environment interaction (GE)] biplot graphical tool was used to analyze yield component data. The combined analysis of variance revealed a significant difference (P<0.01) among genotypes, environments and genotype-by-environment interaction for all studied traits. In conclusion, seed yield per plant ranged from 21.7 to 42.1 g, number of seeds per plant ranged from 43.7 to 162.2 and 100-seed weight ranged from 22.9 to 45.7 g. The evaluation of the genotypes in terms of stability showed that Onceler 98, Akdag and A.27 genotypes were more stable in terms of seed yield per plant, A.20, A.21, Onceler 98, Goynuk 98 and Zulbiye genotypes were more stable in terms of seed number per plant and Yunus 90 was more stable in terms of 100-seed weight. GGE biplot facilitated the visual comparison and identification of superior genotypes according to their yield performance.
