GENETIC VARIABILITY OF COMMON BEAN (Phaseolus vulagris L.) GENOTYPES GROWN IN KARAMILE, EAST HARARGE, ETHIOPIA

Abstract:

The purpose of this study was to estimate the extent of genetic variability of agronomic traits and their contribution to seed yield. Twelve quantitative characters genotypes of common bean was studied. The experiment was conducted at karramille farmer’s field as randomized complete block design planted in three replications. Results showed that genotypes with more yields were identified as Tinike for maximum seed yield per plants with values of (120g), Awash-melka for seed per plant (264) and for hundred seed weight(98.33g). The genetic advance as percent of mean (GAM) ranged from 1.167% for number of pods per plants to 104.15% for hundred seed weight. Genotypic coefficient of variation ranged from 2.275 (days of flowering) to 54.663 (Hundred seed weight) while phenotypic coefficient of variation ranged between 2.548 (days of flowering) and 59.187 (Hundred seed weight).While High genotypic coefficients of variations(GCV) were observed for plant height (45.31),harvest index(26.6938) ,hundred seed weight (54.66), above ground dry biomass(42.44), number of seed per plants (44.83) and seed yield per plant(45.98). High phenotypic coefficients of variations (PCV) were observed for, plant height (49.17), number of pod per plants (35.31), number of node per plant (24.05), number of seed per plants (45.78), above ground dry biomass (43.60), hundred seed weight(59.18734), harvest index ( 29.53),and seed yield per plant (47.77).Seed yield per plant had positive and significance different with related to biological yield (0.398) and hundred seed weight (0.349) as well as positive and highly significant difference with related to number of seed per plant (0.52) and harvested index (0.61). The genotypic path analysis had the maximum positive direct effect of biological yield (0.978) on seed yield constitutes the major portion of the total correlation between biological yield and seed yield (rg=0.834). The maximum positive direct effect of harvest index (0.9078) on seed yield constitutes the major portion of the total correlation between harvest index and seed yield (rp=0.6155).
