Abstract

During 1975, 145 additional soybean (Glycine max [L.] Merr.) Plant Introductions and cultivars belonging to Maturity Groups 00-IV were evaluated in the screen house for corn ea rworm (Heliothis zea Boddie) resistance. The experimental procedures were the same as described in the previous article except the number of corn earwonn moths released in the screen house; 2,872 moths (2,244 released in 1974) were released from June 24 to September 19, 1975 . Since a positive phenotypic correlation between the number of pods per plant and yield has been reported by many scientists (Anand and Torrie, 1963; Hanson and Weber, 1961; and Weatherspoon and Wentz, 1934), it is hoped that Plant Introductions and cultivars capable of producing more undamaged pods under heavy infestation will be both resistant and high yielding
