An investigation was carried out on studies on Influence of different genotypes on growth, yield and quality parameters at ICAR-KVK, Hagari, Benchikottal, Ballari, during 2020-21 with thirty two onion genotypes in three replication. The growth characters appeared significant difference among the genotypes evaluated. The genotype ONVC-24 exhibited maximum plant height (68.26 cm). The genotype ONVC-04 exhibited maximum number of leaves per plant (14.12). The genotype ONVC-23 exhibited maximum leaf length (62.26 cm). The genotype ONVC-08 exhibited maximum leaf area (441.44 cm2) and leaf area index (3.32). The genotype ONVC-20 exhibited maximum average bulb weight (124.73 g), total yield per plot (15.22 kg), and marketable yield per hectare (76.11 t). The genotype ONVC-18 registered maximum longitudinal diameter of bulb (6.40 cm). The genotype ONVC-25 recorded maximum equatorial diameter of bulb (6.40 cm). The genotype ONVC-29 registered maximum number of rings per bulb (12.72). The genotype ONVC-05 recorded maximum thickness of onion scale (0.45 mm). The genotype ONVC-24 recorded highest days to maturity (120.81 days). The genotype ONVC-08 recorded maximum total soluble solids (13.76 0B). The genotype ONVC-14 recorded maximum bulb neck thickness (1.09 cm). The genotype ONVC-10 recorded highest bulb shape index (1.46). The genotype ONVC-04 recorded highest dry matter of onion percentage (17.55%). The onion is an important crop with many medicinal values, it has good yield and quality attributes. Thus identification of promising varieties as a commercial crop for the area with high yield and quality fruits would help the farmers in its adoption and improving their economic status.
