Abstract

Segregating populations arising from crosses involving two sources of Mexican bean beetle (Epilachna varivestis Mulsant) resistance were screened and selected for resistance to velvetbean caterpillar (Anticarsia gemmatalis Hubner) in Guaiba, Rio Grande do Sul , Brazil and Isabel a, Puerto Rico. The Mexican bean beetle resistant cultivars used in the crosses were PI 171.451 and PI 229.358 (Van Duyn et al., 1971). The materials tested came from two sources: Dr. R. L. Bernard of the USDA Regional Soybean Laboratory, Urbana, IL and Dr. S. G. Turnipseed of Clemson University, Blackville, SC.
