Evaluation of Genetic Variations and Agronomic Performance of Some Selected Pepper Landraces in Obio Akpa, Akwa Ibom State – Nigeria
Abstract
The research was conducted in 2023 at the Teaching and Research Farms of the Faculty of Agriculture, Akwa Ibom State University, Obio Akpa campus, to evaluate the Genetic Variation and Agronomic Performance of some Selected Pepper Land races. The experiment followed a Randomized Complete Block Design (RCBD) with three replications in a split-plot arrangement. Treatments consisted of five pepper varieties: Tatachi, Danjarawa, Yellow Variety, Ayadowo Long Variety and Ayadowo Short Variety. The growth parameters observed were plant height, number of branches per plant, number of flowers per plant, number of fruits per plant, number of seeds per fruit, stem girth, fruits weight and fruit length. Results showed that there was no significant difference in plant height, stem girth, number of branches per plant, number of flowers, and number of fruits per plant among the five varieties. However, there was a significant difference in number of seeds per fruit, weight of fruit and fruit length. The results of the phenotypic and genotypic coefficient of variation shows that genotypic coefficient of variability (PVC) was higher than the genotypic variance and GVC for all the characters, suggesting the influence of the environment in the expression of these characters. Genotypic coefficient of variation was low for plant height (1.55), number of branches per plant (3.67) and moderate for number of flowers per plant (18.53) and was high in number of fruits per plant (38.79). Phenotypic coefficient of variation was low for number of branches per plant (8.54), moderate for plant height (17.69), but high for number of fruits per plant (102.00) and fruit weight per plant (80.15). Among all, Tatachi was the highest performer for all the fruit quality trait which is a signal for genetic variability that could be used for improvement. The least performer was recorded from yellow variety.
