Role of Ry_chc gene diversity in the resistance of wild potato relative Solanum chacoense to potato virus Y.

ABSTRACT: Potato virus Y (PVY) is one of the most significant pathogens in the production of cultivated potato Solanum tuberosum worldwide. The most efficient way to combat viral diseases is the use of resistant varieties. The Ry_chc gene was discovered in the tuber-bearing wild potato relative Solanum chacoense. This gene is able to confer extreme resistance to PVY by rapidly halting virus multiplication in plants without the development of visible symptoms. Two molecular markers were developed to predict the presence of the Ry_chc gene and PVY resistance with 100% accuracy. In this study, the diversity of the Ry_chc gene and its relationship with resistance to PVY were investigated in genotypes from the Russian potato genbank. A collection of 60 genotypes originating
