The study was conducted at Teaching and Research Farm, Faculty of Agriculture, Bayero University, Kano (Lat 11 0 59`N, Long 8 0 25`E and 466m above sea level), during 2016 rainy season, to determine the variability, heritability and correlation among the soybean varieties. The treatments consist of eight soybean varieties, laid out in Randomized Complete Block Design (RCBD) and replicated four times; varieties were evaluated for fifteen characters to determine variability, estimate heritability and correlation. Analysis of variance revealed significant difference (P>0.01<0.05) with respect to four characters and highly significant (P≤0.01) four seven characters. The results indicated the presence of substantial variability among the varieties. GCV, PCV, ECV and heritability estimates ranges from 0.000039-169.18, 0.000066-187.55, 0.000053-122.28 and 0-100% respectively, the high Genotypic Coefficient of Variation (GCV), Phenotypic Coefficient of Variation (PCV) and Environmental Coefficient of Variation (ECV) observed in this study indicated the existence of variability and selection can be done. Whereas high estimate of broad Sense heritability for the tested parameters indicated that these characters were highly heritable and selection can be imposed. Significant phenotypic correlation for GWha and FWha with FWP respectively revealed that, these characters were primarily influenced by their direct contribution to higher yield. It is therefore recommended for an effective selection of those characters could be adopted for cultivar improvement and hybridization program and more research is needed to validate the findings.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
