Realizing the importance of germplasm in building up resources for future commercial exploitation, the Department of Horticulture, Mahatma Phule Krishi Vidyapeeth, Rahuri, undertook a detailed survey of traditional and nontraditional onion-growing areas of the state of Maharashtra, and India in general, and collected 148 red-skin and 33 white-skin types of onion. These landraces are being maintained and evaluated for their growth, bulb, and yield characters. The results of the experiment conducted during the rainy season of 1991 indicate that red-skin cultivars IC 800050 and IC 890164 exhibited a maximum average bulb weight of 100 g while white-skin cultivars IC 800011 and IC 800106 produced a maximum average bulb weight of 82 g.

The minimum average number of centres per bulb was 1.2 found in red- types IC 800007, IC 800008A, IC 800044, IC 800046, and IC 800120, and 1.0 in white type IC 800027.

The maximum total soluble solids (TSS) of 14.9% was observed in red type IC 800046 and in white type IC 800033. These cultivars hold promise for further exploitation in breeding programmes.
