Genetic Variability of Early Maturing Advanced Potato (Solanum tuberosum L.) Hybrids

Genetic variability was studied among 11 early maturing potato hybrids. The genotypes showed large variation for yield and yield components at phenotypic and genotypic levels. High genetic advance (% of mean) values coupled with high heritability was observed in character like plant height, number of tubers per plant, marketable tuber yield, total tuber yield, tuber diameter, non-reducing sugars, leaf roll and Spodoptera. However, the estimates were moderate for number of leaves, tuber dry matter, reducing sugars and total sugars. These traits would be improved through simple selection methods. J/97–168 and Kufri Pukhraj were found to be promising.
