Screening of different varieties of pomegranate against Scirtothrips dorsalis Hood

Abstract

Screening of different commercial and ornamental cultivars of pomegranate was done with two different parameters. One by counting actual number of thrips found per plant and by per cent infestation of thrips found per plant. Investigations were carried out for the research work on “Screening of different varieties of pomegranate against Scirtothrips dorsalis Hood.” The pooled data presented in tables reveled that among fruit bearded cultivars ‘Ruby’ recorded least per cent fruit infestation (52.14) which is found significantly superior over rest of the treatments followed by ‘Nayna’ recorded 64.44 per cent fruit infestation, ‘Ganesh’ recorded 67.45 per cent fruit infestation and ‘Bhagwa’ recorded 72.67 per cent fruit infestation all these are found second most resist treatments and at par with each other. As usual ‘Mridula’ recorded highest per cent fruit infestation (80.05) followed by Ja. Seedless and ‘Arakta’ which were recorded as 78.48 and 78.23 per cent fruit infestation per plant respectively.With this given pooled data most resistant cultivar is enlisted with decreasing order other than Daru and Nana was as like this: Ruby > Nayna > Ganesh > Bhagwa > G-137 > Arakta >Ja. Seedless > Mridula. ‘Ruby’ is highly resistant while ‘Mridula’ is highly susceptible cultivar among commercially used cultivars.
