<abstract>Pepper genotypes were evaluated to estimate the magnitude of genetic variability, relationship of traits and their contributions to yield. Results showed highly significant differences (P≤0.01) among the genotypes of pepper as Scotch bonnet genotype produced the highest fruit yield per plant and fruit yield per hectare of 315.8g and 12.6t/ha when compare to other genotypes. High broad sense heritability was recorded for all the plant attributes. Cluster analysis grouped the genotypes into three clusters. Principal component analysis showed that number of fruits per plant, fruit yield per plant and fruit yield per hectare contributed more to the variations observed in pepper. Correlation analysis showed that fruit yield per hectare had positive and significant assocition with fruit yield per plant (r=0.9**), number of fruits per plant (r =0.6*), fruit length (r=0.6*) and fruit circumference (r=0.6*), indicating that fruit yield per hectare can indirectly increased by selection of plants with the above mention traits. Applications of breeding strategy will improve productivity of pepper since there is existence of genetic variability among genotypes as progress in breeding depends on it.</abstract>
