P.G. Eruotor, M.S Zanzam, S.A.Hashim Yam, genotypes, tuber yield, character, correlation 10-20 8(1) 2024 January 2024 The current study was conducted at the Taraba State University, Jalingo, Taraba State, Nigeria during 2022 cropping season to investigate the magnitude of genetic variability, correlation and path analysis. Ten yam genotypes were evaluated in a randomized complete block design with three replications. The result revealed the presence of significant difference (p≤ 0.01) for all the characters except percentage emergence and number of leaves. High genotypic and phenotypic coefficient, heritability and genetic gain were observed for petiole length, number of tubers per plant, weight of tubers per plant, weight of tubers per plot and tuber yield per hectare. Correlation analysis showed that tuber yield per hectare exerted significant and positive correlation for weight of tubers per plot, weight of tubers per plant, and number of tubers per plant. Path analysis revealed that weight of tubers per plot, petiole length, and tuber width exerted higher positive direct effect on tuber yield. These traits can be considered to be determinant for yield improvement in yam.
