A. A. HAKRO, S. A. JAMIL KHAN AND S. A. H. JAFFRY
Abstract
Seeds of eight varieties of sorghum viz., Acchokartuho, Depar, Ghotki, Redjanpur, Rehmani, Sarakartuho, T3 and T5 collected from the ARI. Dadu were inoculated with fresh inoculum of grain smut (Sphacelotheca sorghi) and planted at CDRI field during the year 2000. Sorghum varieties varied significantly in their resistance to the disease. T3 with 10% infected heads was the most resistant whereas Rehmani with 32.6% head infection appeared to be the most susceptible followed by Sarakartuho (25.7%), Acchokartuho (21.1%), Ghotki (18.1%), Depar (12%), T5 (11.5%) and Redjanpur (11.1%). There is need to evolve high yielding disease resistant sorghum varieties for increasing sorghum grain production.
