Heritability, Genetic Advance and Character Association in Six Yield Related Characters of Solanum anguivi

O.A. Denton and C.C. Nwangburuka
The objective of this study was to assess eighteen accessions of Solanum anguivi collected from various diverse sources for broad-sense heritability, genetic advance and character of association in yield related traits. The experiment was laid out in a Randomized Complete Block Design (RCBD) with four replications. High estimates of broad sense heritability was observed in plant height at maturity (76.67), number of branches per plant (83.9), total number of fruits per plant (85.5), total weight of fruits per plant (86.96) suggesting additive gene effect in these characters. Number of branches per plant, total number of fruits per plant, total weight of fruits per plant combining high estimates of heritability and genetic advance is an indication of crop improvement through mass selection. Positive and significant phenotypic and genotypic correlation was observed between number of branches and total number of fruits per plant (0.67, 0.74) and total weight of fruits per plant (0.61, 0.67) suggested that selection for fruit yield on the basis of these traits will be effective. Meanwhile, significant and negative phenotypic and genotypic correlation between number of fruits per plant and fruit length (-0.30, -0.41) suggested that selection for fruit yield on the basis of these traits will not lead to increases in fruit yield.
