Screening of peanut cultivars against colonization of Aspergillus flavus

Ten groundnut cultivars were employed for the studies on in vitro pod and seed colonization by A. flavus. None of the cultivar was found to be free from A. flavus colonization. Pod colonization ranged from 26.67 to 63.33 percent on 5^th day of incubation while 43.33 to 90.00 per cent on 7^th day of incubation. Minimum colonization (26.67%) was recorded on Phule Unnati which was at par with Phule Unap (28.33%) and Phule Vyas (31.67%). Maximum colonization was recorded on JL-24 (71.67%) on 5^th day of incubation. Similar trend was observed on 7^th day of incubation. Kernel colonization severity ranged from 25.00 to 55.00 per cent on 5^th day of incubation, while 40.00 to 83.33 per cent on 7^th day of incubation. Minimum colonization severity was recorded on Phule Unnati (25.00%), Phule Unap (25.00%) and at par with Phule Vyas (28.33%) while maximum colonization severity was recorded on JL-24 (55.00%) on 5^th day. Similar trend was observed on 7^th day of incubation.
