ABSTRACT The experimental work was conducted in the field No. 11 at the Research Farm of R.A.K. College of Agriculture, Sehore, Madhya Pradesh under, All India Coordinated Research Project on soybean financed by ICAR, New Delhi. Four replications (2treated + 2 untreated), treatments 50 Soybean genotypes/varieties. The grain yield range from 456.25 to 2375.00 kg/ha and 437.50 to 2263.00 kg/ha, in treated and untreated varieties, respectively. The grain yield loss % ranged from 0.67 to 17.71 percent in different varieties. These varieties were further grouped in four categories, based on the maximum - minimax method. Ten varieties were resistant, high yielding (R-HY), sixteen were resistant, low yielding (RLY), Twenty three varieties were susceptible low yielding (S-LY) and one variety was susceptible high yielding (S-HY).
