DIFFERENTIAL REACTION AND SOURCE OF RESISTANCE TO WILT CAUSED BY PSEUDOMONAS-SOLANACEARUM IN BRINJAL (SOLANUM-MELONGENA)

An experiment was conducted during winter season of 1990-91 to 1992-93 to study reaction and source of resistance to wilt caused by Pseudomo nas solanacearum Smith in brinjal (Solanum melongena L.) in bacterial sick plot. Only 5 local accessions ('CH 243','CH 245', 'CH 247','CH 24 9' and 'CH 309') of brinjal showed resistant reaction (0-20% wilt) in the mean data of 3 years to this disease. Among these 'CH 245', 'CH 24 9' and 'CH 309' were found stable for resistance as well as for high y ield potential. Out of 15 genotypes proved moderately resistant, 6 loc al collections ('CH 157', 'CH 242', 'CH 246','CH 277','CH 278' and 'CH 306') gave high yield. Of the 6 high-yielding collections, 'CH 157' a nd 'CH 278' were found stable in yield as well as reaction to wilt. Th e resistant as well as moderately resistant. stable genotypes may be u sed as donor parent in breeding programme. Among the highly susceptibl e genotypes, 'CH 152' was found high yielder.
