STORAGE BEHAVIOUR OF POTATO VARIETIES AND ADVANCED CULTURES AT ROOM TEMPERATURE IN BIHAR

Abstract

Storage behaviour of six newly released and seven old Indian potato varieties along with three exotic varieties and four advanced hybrids was studied for two years under ampient temperatures during mid March to mid June, at Central Potato Research Station, Patna in eastern plains. No marked variations in sprouting and keeping quality were observed in the varieties and hybrids under test, while cv. Kufri Ashoka was found to be a poor keeper. All the varieties and hybrid showed dormancy ranging 8 to 9 weeks. The study indicated that more emphasis needed to be placed on these characters along with yield to have better keeping varieties for export and domestic consumption.
