Identification of candidate loci for leafing date in Iranian walnut germplasm collection using GBS-GWAS approach and validation by SNaPshot.

Abstract excerpt

Late-spring frost is increasingly damaging walnut orchards worldwide, underscoring the urgent need for late-leafing cultivars adapted to climate instability. Despite extensive genomic resources in Juglans regia, additional robust markers for leafing date are still needed to enhance breeding efficiency. Here, we combine high-density genotyping-by-sequencing (GBS) with multi-model genome-wide association analysis...
