Abstract
Genetic variation, broad sense heritability, and expected genetic advance were studied in a collection of 16 established cultivars of pepper (Capsicum annuum L.) collected from diverse ecological zones of Nigeria ranging from semi-arid to tropical rain forest. Most of the characters studied had high genetic variance estimates. The highest genotype x environment interaction variance was recorded for yield per plant. Broad sense heritability estimates were high for all characters except days to maturity. The estimates ranged from 37.36 percent for days to maturity to 99.11 percent for number of branches per plant. The expected genetic advance in percent of mean ranged from 1.01 to 129.17 for days to maturity and number of branches per plant respectively. In general, the results obtained indicate that yield improvement could be achieved through direct selection for number of fruits per plant, plant height, and number of branches per plant.
