A field experiment was conducted to ascertain the production potential of different onion varieties and to identify the most suitable high yielding varieties with better growth, yield and quality. The experiment was carried out during the rabi season of 2019-20 at the experimental research farm of RLBCAU, Jhansi. Nineteen onion varieties were evaluated in Randomized block design with three replications. The data analysis revealed sufficient variability among all the genotypes for all the studied traits. The results depicted that, NHRDF Red-4 performed better with respect to majority of the yield and contributing traits and it can be further considered for multiple trials for further evaluation. The highest number of leaves, Polar diameter of bulb, leaf diameter was recorded in the variety Pusa Sona.
