Storage behaviour of 16 promising potato genotypes against two standard varieties as check were studied under natural storage condition for 150 days at Regional Agricultural Research Station, Jamalpur during 1992-1993. Genotypes like 86.844, 86.315 and 88.163 exhibited extended dormancy varying from 118 to 1250 days while the genotypes 87.272, 87.494, 87.221 and 87.410 had short dormancy varying from 77 to 84 days. Sprout length, sprout weight and sprouting efficiency were higher but number of growing sprouts were lower in short dormants and vice versa in extended dormants. Tuber weight loss was gradual for the first 90 days, thereafter, it registered a sudden increase. Short dormants shrunk earlier than the extended ones.
