Multiple disease resistance in different Brassica genotypes
Abstract
Different genotypes of Brassica juncea, B. carinata, B. napus and B. rapa were evaluated under natural,
and artificial inoculation field conditions against white rust, Alternaria blight and Sclerotinia rot diseases
during 2004-05 to 2008-09. Nine germplasm lines including EC-414291, EC-414293, PT-303, GSL-1, BINOY
(B-9), LES-39, NPJ-109, HNS-0004 and BIO-Q-108-2000 exhibited white rust intensity below 5% consistently
under 3-4 years. Brassica germplasm PHR-2 and GSL-1 showed resistance against Alternaria blight
consistently in 2 years of field testing. Ten Brassica germplasm including BIOYSR, PHR-2, JMT-04-03,
RHO-304, NRCHB-04-06, NRCDR-705, PWR-2011, RRN-608, RRN-609 and EC-399301 exhibited
Sclerotinia rot incidence below 5% consistently under 2 years of evaluation.
