Abstract:
Field experiments were conducted during 2010-11 to 2011-12 crop seasons to identify resistant genotypes for the management of bacterial blight/black rot caused by Xanthomonas campestris pv. campestris (Pammel) Dawson. Symptoms of disease were recorded 40-45 days after sowing in different localities of Faizabad district of U.P. Disease was characterized by the initial symptoms appeared as dark color streaks on the stem from ground level, which girdle the stem making very soft and hollow followed by rotting. Lower leaves showed midrib cracking ‘V’ shaped yellowing on the leaf margin, browning of veins and weathering. Profuse exudation of yellowish fluid from the affected stem and leaves may also occur. Out of 110 genotypes screened, ten entries namely T-27, GSL-1, PHR-2, DRMR-243, PBC-9221, JMTA-9, EC-399299, EC-38899, HNS-9605 and HNS-004 were recorded resistant and forty four were moderately resistant. Rest of the genotypes proved moderately susceptible from X. campestris pv. campestris.
