An experiment was conducted at the Horticultural Farm, Bangladesh Agricultural University (BAU), Mymensingh during the period from October 2010 to April 2011. The present study was aimed at determining the effect of vernalization on the yield of onion seed. The experiment consisted three levels of Vernalization (viz., vernalization of mother bulbs at 50C ± 1 and 100C ± 1 and no vernalization). Bulbs of 20±1g size of local cultivar Taherpuri were used as planting material and were vernalized at the duration of 14 days in freezing. Yield and quality of onion seeds significantly influenced by vernalization. Bulbs were vernalized in a refrigerator at a calibrated temperature of 5 ± 10C and 10 ± 10C. Plant produced from the bulbs vernalized at 5±1o C temperature prior to planting gave maximum leaves at 15, 30 and 45 DAP (19.91, 26.47 and 30.84 leaves per plant, respectively). Maximum seeds (189.05g) per umbel were produced by the plants that were vernalized in 5±10C. The highest seed yield per plot (915.89g) was found from the cold treatment at 5±10C. Early plant emergence was noticed for longer vernalization treatment. Cold treatment of mother bulbs influenced the plant to produce maximum number of leaves.
