Evaluation of a set of 43 diverse genotypes of Soybean was carried out for their pre-harvest sprouting (PHS) tolerance and other important agroeconomic traits. Significant differences among the various characters of the genotypes under study were revealed through analysis of variance. Seed germination % in pods (SGP), was used as a measure of PHS tolerance. It ranged from 10.23 in DSb 30-2 to 74.4 in the cultivar JS 20-116. The character association studies revealed significant association of various plant, pod and seed traits with pre-harvest sprouting in soybean. The study also provided information on the performance of some of the popular soybean cultivars with respect to their PHS tolerance and identified some soybean genotypes with relatively low PHS. However, comprehensive field evaluation is required before these genotypes can be used in breeding programmes
