Abstract:
The current investigation aimed to assess the genetic variability, heritability and genetic advancement as a percentage of the mean for 18 attributes related to the growth, yield and quality of orange-fleshed sweet potato (Ipomoea batatas) using 27 different genotypes. This study followed a Randomized Block Design with three replications during the rabi season of 2022-23 at the Dr. YSRHU-Horticultural Research station in Peddapuram.
The current investigation aimed to assess the genetic variability, heritability and genetic advancement as a percentage of the mean for 18 attributes related to the growth, yield and quality of orange-fleshed sweet potato (Ipomoea batatas) using 27 different genotypes. This study followed a Randomized Block Design with three replications during the rabi season of 2022-23 at the Dr. YSRHU-Horticultural Research station in Peddapuram.
The analysis of variance showed significant differences among the genotypes for all the characteristics examined. Most traits exhibited high levels of Phenotypic Coefficient of Variation (PCV) and Genotypic Coefficient of Variation (GCV), except for leaf lobe length, number of leaves per vine, tuber length, tuber girth, dry matter content and beta carotene content. This suggests a wide range of variability and a broad genetic foundation, with minimal environmental influence. These traits are primarily under the influence of additive genetic effects, indicating potential for improvement through simple selection methods.
Furthermore, a high heritability (greater than 60%) and a substantial genetic advance as a percentage of the mean (over 20%) were observed for all attributes, except for leaf lobe length and tuber girth. This indicates that additive genetic effects predominantly influence these traits, making direct phenotypic selection a useful approach for improvement.
