Assessment of Potato (Solanum tuberosum L) Hybrids-Varieties for Table Purpose Among Yield and Quality Traits

To explicated Genetic variability of total 24 potato genotype for table purpose potato with two different sets viz., 75 days and 95 days of harvest. A wide range of phenotypic variability was recorded for reducing sugar, plant height, average weight oftubers, number of tuber per plant and tuber dry matter content. The high genotypic coefficient of variation (GCV) were observed for reducing sugar, number of stem per plant, marketable tuber yield and chip color. While high phenotypic coefficient of variation (PCV) observed for marketable tuber yield and number of stem per plant. High heritability valuewas noted for reducing sugar (99.98 and 99.96) in 75 days and 95 days of harvest, respectively. The highest value of GA (% mean) observed for reducing sugar 95.34 (C₁) and 97.24 (C₂). The average weight of tuber, number of tuber per plant, number of stem per plant and marketable yield exhibited significantly positive correlation with number of tuber per plant at bothgenotypic and phenotypic levels. The path coefficient analysis revealed higher positive direct effect on total tuber yield for marketable yield.
