ABSTRACT
The status of host-plant resistance was evaluated in pearl millet (Pennisetum glaucum L.) against aphid species greenbug, Schizaphis graminum (Rondani). It was determined by the ability of seedlings to resist for plant stunting caused by aphid's feeding at seedling stage. The results indicated that out of 135 pearl millet entries tested, 21 were resistant, 69 were moderately resistant and 45 were susceptible to greenbug feeding. The resistant entries were: C-591, Pak-75211, Pak- 75212, Pak-75219, Pak-75194, Pak-75227, Pak-75238 Pak-75272, Pak- 75276, WCA-78, C-47, Pak-75322, Pak-75323, Pak-75329, Pak-75331, Pak- 75334, Pak-75337, Pak-75338, Pak- 75339, Pak-75353 and Pak-75359. The entries resistant or moderately resistant with damage rating< 4 in the present studies may be used in any breeding programme to reduce greenbug damage, whereas the susceptible entries should be avoided.
