Its excellent agronomic traits, including resistance to biotic and abiotic stresses, make it a potential genetic donor for interspecific hybridization. <i>Myzus persicae</i> (green peach aphid, GPA) is one of the most harmful pests of <i>Brassica</i> crops, significantly effecting the yield and quality. However, few aphid-resistant <i>Brassica</i> crop germplasms have been utilized in breeding practices, while the underlying biochemical basis of aphid resistance still remains poorly understood. In this study, we examined the genetic diversity of 75 <i>B. carinata</i> accessions and some plant characteristics that potentially contribute to GPA resistance.
