Field evaluation of cotton genotypes against bacterial blight caused by Xanthomonas axonopodis pv. malvacearum

摘要

One hundred and eighty two genotypes of cotton were evaluated against bacterial blight under field inoculated conditions (artificial screening) at Regional Agricultural Research Station, Guntur during 2007-2008 to 2009-2010. Twenty one genotypes viz.,NDL 762, TCH 1716, RS 2527, P 1752, HAG 1015, CNDTS 55, RAH 61, ARBHH 51, RAHH 255, INDAM 1020, NSPL 423, TCHH-2, HHH 455, LMSH 263, HAGHH 2064, JKCH 2516, PHH 177, ARBH 2040, RAHH 138, MRC 7361 and DHH 852 were recorded resistant and 70 showed moderately resistant reactions. These resistant genotypes can be used in breeding programmes.
