Differential reaction and source of resistance to wilt caused by Pseudomonas solanacearum in brinjal (Solanum melongena)

Abstract

An experiment was conducted during winter season of 1990-91 to 1992-93 to study reaction and source of resistance to wilt caused by Pseudomonassolanacearum Smith in brinjal (Solanum melongena L.) in bacterial sick plot Only 5 local accessions ('CH 243', 'CH 245', 'CH 247', 'CH 249' 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 249' and 'CH 309' were found stable for resistance as well as for high yield potential. Out of 15 genotypes proved moderately resistant, 6 local 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' and 'CH 278' were found stable in yield as well as reaction to Wilt. The resistant as well as moderately resistant, stable genotypes may be used as donor parent in breeding programme. Among the highly susceptible genotypes. 'CH 152' was found high yielder.
