Screening of onion varieties against onion thrips, Thrips tabaci Lind

Shaikh, R. R; Acharya, M. F. and Rode, N. S.

A field experiment was conducted at Vegetable Research Station, Junagadh Agricultural University, Junagadh during rabi season of 2012-13 to ascertain the susceptibility of eleven white onion and fifteen red and dark red promising genotypes (with one recommended cultivar in both) of onion to Thrips tabaci. Considering categorization for red onion varieties, Talaja Red, AGFL Red and Pilipatti was categorized as highly resistant, JRO-10-07, JRO-06-17, JRO-07-13 and JRO-1-09 as resistant. JRO-10-12, JRO-12-11, JRO-09-12, JRO-10-11, JRO-12-06, JRO-04-234 as well as JRO-10-06 were found susceptible while, JRO-12-12 grouped into highly susceptible. However among white onion varieties GWO-1 and AWSO-07-10 recorded less thrips population and proved highly resistant. The genotypes JWO-05-07, AWSO-01-2, JWO-05-08 and AWSO-10-3 were categorized into resistant group. AWSO-10-4 and JWO-08-09 were found susceptible. JWO-08-08, AWSO-04-7 and JWO-12-10 recorded highest thrips population and could be categorized as highly susceptible.
