ABSTRACT
Grain mold of sorghum is a serious problem on kharif sorghum in Marathwada region resulting in deterioration of sorghum grains both qualitatively and quantitatively. Present study was aimed to pinpoint predominant fungi associated with the problem. Study indicated predominant association of F. moniliformae, C. lunata and P. sorghina. Pathogenicity study revealed that CSH-9 was more vulnerable to infection of these molds than CSH-16. Similarly, milk stage of grain development was highly susceptible, while physiological maturity stage resisted to grain mold infection. Interaction study indicated more susceptibility of CSH-9 harvested at milk stage. Grains harvested at physiological maturity of both the hybrids were less susceptible. C. lunata infected more to CSH-9 and CSH-16 hybrids which was on par with CSH-9 for F. moniliformae. Rest of the fungi was less aggressive. Milk stage of grain development of these hybrids was more vulnerable to F. moniliformae and C. lunata. Infection of F. moniliformae and C. lunata grew rapidly on sorghum grains than P. sorghina.
