Abstract

Maize is an important crop of Himachal Pardesh. Erwinia Stalk Rot (Erwinia chrysanthemi pv zeae) and Brown stripe Downy mildew (Sclerospora rayssiae var zeae) take a heavy toll of maize in the state. two hundred twenty one hybrid and composite stock received from Director of Maize Reserch, New Delhi were evaluated against erwinia Stalk Rot (Erwinia chrysanthemi pv zeae) and bbrown stripe downy mildew (Sclerospora rayssiae var zeae) during 2009 & 10 kharif season under natural epiphytotic conditions. It was observed that seven stocks viz, HKH407, JH12114, JDX-2901, BMH-109, MCH-40, KH-105 and Bio 9681 were highly resistant and twenty one stocks were found resistant to Erwinia stalk rot. Ten stocks viz CMH 108–154, JH-12114, IDX-2901, PAC–T99, BIO-265, JKMH-31314and KMH-3426 were highly resistant and 22 stocks were resistant to brown stripe downy mildew. Superior resistant entries may be evaluated for release as varieties or exploited in breeding programme.
