The study was conducted to assess the extent and nature of genetic variability, heritability and genetic advance among the different thirty five potato genotypes for growth, yield and processing quality attributes over two seasons during kharif and rabi-2021. Results of analysis of variance revealed significant differences among the potato genotypes for different parameters. For all the characteristics evaluated, phenotypic coefficients of variation were higher than genotypic coefficients of variation. The phenotypic coefficients of variation (PCV) and genotypic coefficients of variation (GCV) were found high for weight of tubers per plant (g), tuber shape, number of branches and marketable tuber yield. Range of variability for most of the traits was found high, which indicated ample scope for selection and improvement in these traits. Further, high heritability estimates coupled with genetic advance were recorded for parameters such as plant width, plant height, weight of tubers per plant and marketable tuber yield which revealed the presence of additive gene action in expression for these characters. Thus variability, heritability and genetic advance in combination provide a clear picture regarding the effectiveness of selection for improving the characters. Hence, this information in identified genotypes and traits could be used for future potato breeding programs. [ABSTRACT FROM AUTHOR] |
