Abstract: Grain mold is a major disease of sorghum that effects grain production and quality. The disease is very important in improved cultivars with short and medium duration which flower and mature earlier in the rainy season, when soil moisture levels are generally more favorable for grain filling which potentially give higher yields. However, the earlier flowering often results in exposure of developing grain exposed wet conditions in which it can deteriorate rapidly. To overcome this problem, it is essential to identify grain mold resistant hybrids. Sorghum (Sorghum bicolor (L.) moench) cultivars exhibiting contrasting reactions to the grain mold complex and there is always bias with visual scoring systems to score disease severity. Identification of kernel properties associated with resistance to grain mold would useful in screening of breeding material; thus, grain density and germination percentage are two import kernel properties to appraise the grain mold resistance. Twenty five hybrids were selected based on their visual rating for grain mold resistance from replicated trials at two locations in India during 2004 and 2005 rainy seasons and grouped into resistant hybrids and susceptible hybrids. Grain mold resistant hybrids exhibited more grain density (1.19 g mL-1) compared to mold susceptible hybrids (1.10 g mL-1). Germination percentage indicating the seed viability and germination decreased with extent of grain mold incidence. Grain density is an important physical parameter to resist the entry of fungi into the grain. The grains which contain hard endosperm will offer more resistance and also show the high germination percentage.
