Allium cepa var. aggregatum, genotypes, yield, quality


Field experiment was conducted with twenty local genotypes of aggregatum onion (Alliumcepa L.var.aggregatum Don.) collected from Tamil Nadu during 2017-2018 at the experimental field of Department of Vegetable Crops, Horticultural College and Research Institute, Tamil Nadu Agricultural University, Periyakulam to identify the superior aggregatum onion genotypes for high yield and quality. Among the 20 genotypes evaluated, significant variations were observed for the traits viz., Plant height (cm), leaf length (cm), number of leaves per plant, bulb length (cm), bulb diameter (cm), bulb colour, number of bulbs per clump, fresh weight of bulb (g), dry weight of bulb (g), total soluble solids (obrix), pyruvic acid ( µmol g-1). On the basis of high per se performance the genotype Puttarasal (Aca2) recorded the highest plant height, leaf length, bulb diameter, number of bulbs per clump, dry weight of bulb, total soluble solids, and pyruvic acid content. This genotype could be further carried out for producing high yield and best quality onion variety through further breeding programmes.
