Interaction studies of Rhizoctonia bataticolaand Verticilium dtbo-atrum on cotton genotypes

摘要

Seven (RCH-2 Bt, RCH-2 non-Bt, Bunny Bt, Bunny non-Bt, Abhadita, Jayadhar and DH-2) genotypes were used against Rhizoctonia bataticola and Verticillium albo-atrum. These genotypes differed with respect to their resistance or susceptible. In case of Rhizoctonia inoculated pots, there was least germination observed in Abhadita followed by Jayadhar i. e. 40.00 and 46.67%, respectively. With respect to the maximum per cent death of seedlings was observed in DH-2 followed by Jayadhar i. e. 73.33 and 66.67%, respectively. In case of Verticillium. inoculated pots, there was least germination observed in Bunny Bt and Jayadhar followed by RCH-2 Bt i. e. 46.67 and 60.00%, respectively With respect to the maximum per cent death of seedlings was observed in RCH-2 Bt followed by Bunny Btand Jayadhar i. e. 66.67 and 60.00%, respectively.
