Storability study of different short-day onion (Allium cepa L.) genotypes/varieties

A total of 25 short-day onion genotypes along with two recommended varieties viz. BARI Piaz-1 and Piaz-4 were evaluated for 5 ½ months at the bamboo-made ambient storage. The study was conducted Spices Research Sub-Centre, Bangladesh Agricultural Institute, Faridpur, in 2020 geographic coordinates- 23̊ 11̍ N 89̊ 09̍ E. assessing their storability. All trial under accession lines such as AC Bog 409, 410, 411, 412, 413, 414, 415, 416, 417, 419, 420, 421, 422, 423, 424, 425, 426, 427, 428, 429, 430, 431, 433, 434 435. experiment laid out a completely randomized design three replications. storage data recorded periodically 20 days interval (20 May, 08 June, 27 16 July, 04 August, 23 11 September, 30 September 19 October) on rotting (%), sprouting physiological loss weight (PLW, %) (%) bulbs. results revealed that genotypes/varieties had significant difference rotting, sprouting, PLW genotype 430 showed lowest cumulative (10.47%) but 429 exhibited highest (39.47%). maximum minimum losses from (23.03%) (1.47%). (19.39%). However, 420 (44.68%). calculated 433 (79.99%) (44.62%). rate higher May to July than August October. increased increase period. average 20.71%, 13.71%, 29.87% 64.29%, respectively study. capacity not correlated skin colour onion. dry matter content bulb found partial associated capacity. Finally, present storability study, (44.62%), 426 (45.28%), 413 (47.13%) (45.31%) good performance basis loss.
