VARIABILITY, INTER-RELATIONSHIPS AND UTILIZATION OF ANDIGENA POTATO GERMPLASM

Abstract

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 ar.d the minimum for dry matter.
Tuber weight was more important than tuber number in determining tuber
yield. Tuber yield and qualitycharacteristics were not correlated. Promising
genotypes have been identified for use in cultivation or breeding
