Evaluation of soybean breeding lines for corn earworm antibiosis. (Crop Breeding, Genetics & Cytology).(Statistical Data Included)

From: Crop Science | Date: September 1, 2002| Author: Andebrhan, Teklu; Kraemer, Mark; Mebrahtu, Tadesse | Copyright information

Corn earworm (CEW) (Helicoverpa zea Boddie) is the most serious insect pest of soybean [Glycine max (L.) Merr.] and often has reduced yield in much of the Mid-Atlantic and southern coastal plain of the USA. The objectives of this study were to determine the magnitude of genotype x year interaction (GYI) of antibiosis to CEW and to identify genotypes with stable performance. Thirty-two soybean breeding lines, including two susceptible and one line resistant to CEW, were planted in single row...
