Studies on the storage quality of red and white onion allium cepa varieties

Ten varieties of onion, 5 red and 5 white, were studied for their storage quality under ordinary storage conditions at the Punjab Agricultural University, Ludhiana, [India] during 1972. Significant varietal differences for losses in the total weight and the marketable weight were recorded. White varieties were more adversely affected than red varieties. The percentage of rotten bulbs in white and red varieties was the same. The lowest rotting was recorded in S-48 (5%). Sprouting was 85.7% more in red varieties than in white varieties showing its negative association with total soluble solids [T.S.S.]. The bulb weight was negatively correlated with T.S.S. but was not correlated with loss in the total weight, loss in marketable weight and the percentage of rotten bulbs. The total soluble solids had no relationship with loss in the total weight, loss in marketable weight and the percentage of rottenbulbs. The percentage of rotten bulbs was positively related with the loss in the total weight and loss in the marketable weight. Loss in the total weight was closely associated with the loss in marketable weight.
