ESTIMATION OF VARIABILITY, HERITABILITY AND GENETIC ADVANCE AMONG LOCAL CHILI PEPPER GENOTYPES CULTIVATED IN PEAT LANDS
Zulfahmi, F. Yanti, Syafrudin, Juliyanti, Hasrol, Rosmaina
Abstract: Investigation and better understanding on the variability existing in a population base of crop is pivotal to crop improvement so that it can be exploited by plant breeder for crop improvement. The objectives of the study were to estimate the magnitude of genetic variability, heritability and genetic advance for yield and contributing characters of the sixteen of local chili genotypes cultivated in peat land. The experiment was carried out in a randomized complete block design with six replications. Analysis of variance revealed that there are highly significant difference (p < 0.01) among the genotypes tested for all characters studied indicating the presence of variability. In this study, PCV value was relatively greater than GCV for all traits; however, GCV values were near to PCV values for the characters like plant height, stem length, leaf width, fruit Length, fruit diameter, day to flowering, day to first harvest, and single fruit weight indicating high contribution of genotypic effect for phenotypic expression of such characters. High heritability coupled with high genetic advance per percent of mean was obtained for, plant height, stem length; leaf width; plant canopy width, days to flowering, fruit length; fruit diameter, single fruit weight, number of fruit per plant, fruit weight per plant reflecting the presence of additive gene action for the expression of these traits, and improving of these characters could be done through selection.
