Method for the identification of BNYV virus-resistant beet plants Seed and RFLP probe for the implementation of this procedure

摘要

A method for identifying rhizomania resistant beta beet plants or beet seeds and distinguishing them from rhizomania susceptible beta beet plants is described which comprises (a) genomic DNA from a beta beet plant or a beet seed, which has to be analyzed, is treated with a RFLP probe (Restriction Fragment Length Polymorphism probe), capable of combining with genomic DNA linked to genes coding for resistance against rhizomania disease and (b) any genomic DNA comprising genes coding for resistance against rhizomania disease is marked with said RFLP probe. Further a RFLP probe for the identification of rhizomania resistant beta beet plants or beet seeds is described.
