M.M. RAHMAN, M.A. ALI, T.K. DEY, M.R.H. MONDOL AND K.M. KHALEQUZZAMANThe experiment was conducted at Tuber Crops Research Sub-Centre, BARI, Bogra during 2007-2008 to evaluate the reaction of some potato germplasm against stem canker and black scurf of potato under natural infection in the field. Nineteen potato germplasm such as V-4, Quincy, Billini, Meridian, Raja, Innovator Lady Rosetta, Diamant, Lalpakri, Courage, Heera, Ajiba, Cardinal, V-36, BARI-TPS-1, Daifla, Asterix, Felsina and Granola were evaluated. Among the germplasm, only three (Raja, Heera and BARI-TPS-1) were found to be moderately resistant, eight germplasm were (V-4, Quincy, Billini, Lady Rosetta, V-36, Courage, Daifla, Lalpakri) were moderately susceptible and two were susceptible to Rhizoctonia solani.
