Abstract


Anthracnose, caused by Colletotrichum graminicola is one of the most damaging foliar diseases in the world. The most effective and eco-friendly method to control anthracnose is through the insertion of resistant genes. Twenty sorghum genotypes were screened to identify sources of resistance against the disease under field conditions. Out of twenty genotypes, two (PC 5 and ICSB 474) were moderately resistant while, rest were susceptible to highly susceptible during 2014 and 2015 crop seasons. Genotype PC 5 gave least per cent Disease Index (PDI) and AREA Under Disease Progress Curve (AUDPC) whereas, PC 23 showed maximum PDI and AUDPC during both the seasons.
