Assessment of Onion (Allium Cepa L.) Genotypes for Horticultural Traits During Kharif Season

Abstract

The present investigation entitled “Assessment of onion (Allium Cepa L.) genotypes for horticultural traits during kharif season” was conducted at C”-Block farm, Bidhan Chandra Krishi Viswavidyalaya, Kalyani, Nadia, West Bengal during the year 2022- 2023. The experiment was conducted in simple randomized block design (RBD) with seven genotypes and they were randomized in three replications. This Experiment deals with seven different kharif onion genotypes which consist of (viz. DOGR-1627, N-53, Bhima Super, Balwan, Bhima Dark Red, Baswant-780 and Agrifound Dark Red). Through the current investigation the genotype DOGR-1627 was found better than the others in terms of yield (491.49 q-ha), double bulb percentage (2.96 %), neck thickness (5.59 mm) and days taken for maturity (124.67 days) as well as for harvesting (139.00 days). But in terms of quality parameters the genotype Balwan showed maximum Total soluble solids (TSS) of (14.30 ̊ B), Bhima dark red in total sugar percentage (2.47 %), reducing sugar percentage (2.25 %) and the highest polar diameter was recorded from the genotype Basawant-780 (59.57 mm). The genotypes from kharif group could be selected for further improvement and breeding work in future in this particular growing region. Although from the above experiment it may be concluded that in case of Kharif onion, the genotype DOGR-1627 found to be an ideal genotype in respect to marketable yield, neck thickness, double bulb percentage and days taken for maturity.
