D3.4 Report on improved germplasm resistance/tolerance, features and performance
Screening for new varieties or genotypes for their resistance/tolerance to “huanglongbing” (HLB) in citrus was performed in Guadeloupe (France). The work on lethal yellowing (LY) of coconut palm was carried out in Ghana, Mexico and Jamaica. Differences in susceptibility to grapevine yellows (GY) among grapevine varieties suggest the existence of specific genetic features associated with resistance to the phytoplasmas and/or possibly with their insect vectors.
