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

Present investigation was mean to explicated Genetic variability of 24 diverse genotype of potato for table purpose with two different dates (75 days and 90 days after sowing) of harvest. A wide range of phenotypic variability was recorded for reducing sugar, plant height, average weight of tubers, chip colour, number of tuber per plant, tuber dry matter content under bothconditions. The high GCV (%) as well as PCV (%) was observed for reducing sugar, number of stem per plant, marketable yield, chip color, number of tuber per plant and total tuber yield. High heritability and Genetic advance as percentage of mean values were recorded for reducing sugar. The marketable yield exhibited significant and positive correlation with number oftuber per plant, number of stem per plant and total tuber yield at both genotypic and phenotypic levels. The path coefficient analysis revealed higher positive direct effect on total tuber yield for marketable yield.
