Susceptibility response of varieties and local populations of lupines to Bruchus rufimanus (Coleoptera: Chrysomelidae)

This study aimed to evaluate the susceptibility response of varieties and local populations of lupines to Bruchus rufimanus in multi-environment field tests. Seed damaged rate and susceptibility index were assessed in each environment and subjected to a heritability-adjusted genotype and genotype x...
