dc.description.abstractA field experiment on “Genetic Variability, Character Association and Path Analysis Study in Sweet Potato [Ipomoea batatas (L.) Lam.]” was carried out during Kharif, 2019 at Agricultural Research Station, Mandor-Jodhpur (Rajasthan). The experiment was laid out in Randomized Block Design with 16 genotypes and three replications to estimate the extent of genetic variability, heritability, genetic advance, the correlation between yield and other characters, the direct and indirect effect of yield contributing traits through path analysis. Analysis of variance exhibited significant differences for all the characters suggested the presence of great inherent genetic variations among the genotypes. The phenotypic coefficient of variation was slightly higher than the respective genotypic coefficient of variation for all the characters under study. High estimates of heritability and genetic advance as per cent of mean were observed for the characters viz., β-carotene followed by marketable tuber yield per ha, tuber yield per plot, tuber length, TSS, number of marketable tuber per plot, tuber yield per ha, tuber yield per plant, leaf width, tuber diameter, fresh weight of tuber, inter-nodal length, starch content, leaf length and vine length. Moderate heritability was observed for number of tubers per plant and number of marketable tubers plant. Correlation studies among the characters studied revealed that tuber yield per plant has a strong positive significant association with characters like the fresh weight of tuber, number of tuber per plant, starch content, tuber diameter, leaf width, leaf length, inter-nodal length, vine length and tuber length. Path coefficient analysis of various quantitative characters indicated that fresh weight of tuber, number of tuber per plant, tuber length, leaf width, leaf length and tuber diameter exhibited a positive direct effect on tuber yield per plant while, vine length and inter-nodal length exhibited the maximum negative direct effect on tuber yield per plant.en_US
