Soybean Maturity Effect on Expression of Resistance to Lepidopterous Insects

The development of soybean [Glycine max (L.) Merrill] cultivars with resistance to defoliating insects requires characterization of genotypes for the degree of defoliation by natural insect populations in several field environments. Combined analysis of variance over environments for insect defoliation often shows genotype × environment interactions. This research documents the importance of plant maturity and insect seasonality on this interaction (.)
