Interpretive Summary: We present a state-of-the-art multispecies genotyping platform designed for grape, black walnut, chestnut, and hazelnut. This novel array incorporates 70K variants selected to capture the genetic diversity and facilitate high-resolution genotyping across the four economically important fruit trees. To develop this genotyping array, extensive resequencing efforts were made to obtain representative markers from each species' diverse gene pool, ensuring a robust representation of the genetic variation prevalent within each species. The resulting array enables simultaneous interrogation of thousands of markers, providing a powerful tool for various genetic studies in grape, black walnut, chestnut, and hazelnut. This array will provide a cost-effective solution, streamlining genotyping efforts for researchers and breeders working across multiple fruit tree species.

Technical Abstract: Here we present a state-of-the-art multispecies genotyping platform designed for grape, black walnut, chestnut, and hazelnut. This novel genotyping array incorporates 70K single nucleotide polymorphism (SNP) markers selected to capture the genetic diversity and facilitate high-resolution genotyping across the four economically important fruit tree genera. To develop the genotyping array, extensive resequencing efforts were made to obtain representative SNP markers from each species' diverse gene pool, ensuring a robust representation of the genetic variations prevalent within each species. The resulting array enables simultaneous interrogation of thousands of SNPs, providing a powerful tool for genome-wide association studies, linkage mapping, and genomic selection in grape, black walnut, chestnut, and hazelnut. This array provides a cost-effective solution, streamlining genotyping efforts for researchers and breeders working across multiple fruit tree species.
