SCREENING OF SUGARCANE CLONES UNDER ZONAL YIELD TRIALS III, II, I AND ADVANCED YIELD TRIALS AGAINST SMUT DISEASE (USTALIGO SCITAMINEA) IN PLANT CANE

Abstract

A field trial was conducted on sugarcane genotype /clones against sugarcane smut disease (Ustilago Scitaminea) at Bangladesh sugarcane Research Institute (BSRI) farm, Ishurdi, Pubna during the cropping season 2010 -11 for plant cane. Forty-seven clones were inoculated by I g smut teliospore/liter of water equivalent to 105 -106 spore /ml, for 30 minutes mixed with tween 20 for the inoculation of smut spore by dipping method. Among them 32 clones were (R) resistant ,6 Clones were (MR) moderately Resistant, 6 were (MS) Moderately susceptible,2 were (S) Susceptible and only one clone 15-08 highly susceptible found to sugarcane smut disease.
