Abstract
The present investigation was carried out to study screening of 42 groundnut genotypes for early, late leaf spot and rust disease under natural epipytotic conditions in coastal sandy soils at agricultural college Bapatla college farm. Nine genotypes showed resistance against early leaf spot and six each for late leaf spot and rust disease. 21 genotypes showed moderate resistance to early leaf spot and 15 genotypes showed moderate resistance for late leaf spot and rust. Such resistant genotypes can be used for further resistance breeding programme.
