Abstract:

Field experiment were conducted involving 50 aggregatum onion (Allium cepa var. aggregatum) genotypes during 2012-13, 2013-14 and 2014-15 at the experimental field of College Orchard, Department of Vegetable Crops, Horticultural College and Research Institute, Tamil Nadu Agricultural University, Coimbatore to identify the elite aggregatum onion types for high yield and quality. Among the 50 aggregatum genotypes evaluated, significant variations were observed for all the traits viz., plant height (cm), leaves per plant, polar and equatorial diameter of bulbs (mm), average clump weight (g), bulb colour, total yield (t/ha) total soluble solids (°brix) thrips damage (%) and leaf spot incidence (PDI). The per se performance of germplasm revealed that Aca 15 have excelled in yield and contributing characters. On the basis of high per se performance, the potential germplasm Aca 15 (Puttarsal local) recorded the highest plant height of 38.40 cm, number of leaves (19.01), polar and equatorial diameter of bulbs was 39.52 and 42.06 mm, average clump weight (93.46 g), total yield (23.18 t/ha) and total soluble solids (18.69 °brix). Lesser incidence of thrips damage (9.1%) and leaf spot incidence (9.8%) were also recorded in Aca 15. This germplasm could be tested in different seasons over different locations for assessing their stability for high yield and quality.
