Studies on the susceptibility of grains of some sorghum hybrids and varieties to rice weevil and lesser grain borer

Out of four varieties tested the grains of variety 'CSV-5' were found to be the least susceptible to Sitophilus oryzae L. and Rhizopertha dominica F. in storage. Amongst the remaining varieties, grains of 'CSV-4' showed less infestation by both the pests . None of the hybrids tested was found resistant to these pests in storage. However, the hybrid 'CSH-5' was less preferred as compared to 'CSH-1' and 'CSH-6'
