Tuber yield, its component and quality characteristics were studied in 108 genotypes of Andigena potato. Wide genetic variability was found for tuber number, tuber weight, tuber yield and dry matter, percentage vitamin C, proteins, phenols, total sugar and reducing sugars. The maximum variation was noted for reducing sugars and the minimum for dry matter. Tuber weight was more important than tuber number in determining tuber yield. Tuber weight was more important than tuber number in determining tuber. Promising genotypes have been identified for use in cultivation or breeding.
