Development of Cost-Effective SNP Markers for Genetic Variation Analysis and Variety Identification in Cultivated Pears ( spp.).

Pear ( spp.) is a major fruit crop in the Rosaceae family, and extensive efforts have been undertaken to develop elite varieties. With advances in genome sequencing technologies, single-nucleotide polymorphisms (SNPs) are commonly used as DNA markers in crop species.

Low-density SNP markers with high prediction accuracy of genomic selection for bacterial wilt resistance in tomato.

Bacterial wilt (BW) is a soil-borne disease that leads to severe damage in tomato. Host resistance against BW is considered polygenic and effective in controlling this destructive disease. In this study, genomic selection (GS), which is a promising breeding strategy to improve quantitative traits, was investigated for BW resistance.
