摘要：
This study examines the diversity of the Rychc gene in Solanum chacoense, a wild potato relative, and its critical role in conferring resistance to potato virus Y (PVY). The research identifies five alleles of the Rychc gene and establishes a strong correlation between the presence of this gene and PVY resistance. Two molecular markers were developed to accurately predict the presence of Rychc, enhancing the potential for breeding PVY-resistant potato varieties. The findings underscore the importance of genetic diversity in agricultural biotechnology and the potential for improving crop resilience against viral pathogens.
