Hybrid kernels integrating genomic and multispectral data improve wheat genomic prediction accuracy
The Plant Genome, Volume 19, Issue 1, March 2026.Abstract Genomic selection (GS) is transforming plant breeding by enabling more accurate and efficient identification of superior genotypes. However, its practical implementation remains challenging, as achieving high prediction accuracy is critical for its success. Several factors—including sample size, the degree of relatedness among individuals, and
