Common bean rust, Bean golden yellow mosaic virus (BGYMV), Bean common mosaic virus (BCMV), and Bean common mosaic necrosis virus (BCMNV) are devastating diseases of dry bean (Phaseolus vulgaris L.) in Central America and the Caribbean. The development of dry bean cultivars with enhanced levels of genetic resistance to these and other diseases is an important goal of the University of Puerto Rico (UPR) and other dry bean breeding programs in Central America and the Caribbean. PR1572‐19 (Reg. no. GP‐308, PI 692976) and PR1572‐26 (Reg. no. GP‐307, PI 692975) are multiple virus‐ and rust‐resistant pinto bean germplasm lines adapted to the humid tropics that were developed and released cooperatively in 2019 by the UPR Agricultural Experiment Station, the Instituto Dominicano de Investigaciones Agropecuarias y Forestales, and the USDA–ARS. Both PR1572‐19 and PR1572‐26 possess the bgm‐1 gene for resistance to BGYMV, the I and bc‐3 loci that provide broad resistance to all strains of BCMV and BCMNV in the United States and the Caribbean, and the Ur‐3 and Ur‐11 loci that confer comprehensive resistance to all known races of the bean rust pathogen. PR1572‐26 also has the SW12 quantitative trait locus marker associated with resistance to BGYMV. PR1572‐19 and PR1572‐26 produced mean seed yields similar to the check cultivar ‘Santa Fe’ in trials conducted in Puerto Rico and mean seed yields comparable to the pinto cultivar ‘La Paz’ in the Cooperative Dry Bean Nursery conducted in Puerto Rico. Both lines should serve as useful sources of resistance to BGYMV, BCMV, BCMNV, and bean rust for common beans of the Durango race that includes the pinto and great northern market classes.

注册具有广泛的抗锈，BGYMV，BCMV和BCMNV抗性的PR1572-19和PR1572-26斑豆种质系

普通豆锈病，普通豆金黄色花叶病毒（BGYMV），普通豆花叶病毒（BCMV）和普通豆花叶坏死病毒（BCMNV）是干豆的毁灭性疾病（菜豆）L.）在中美洲和加勒比海地区。具有增强的对这些疾病和其他疾病的遗传抗性水平的干豆品种的开发是波多黎各大学（UPR）和中美洲和加勒比地区其他干豆育种计划的重要目标。PR1572-19（Reg。编号GP‐308，PI 692976）和PR1572‐26（Reg。编号GP‐307，PI 692975）是适用于热带潮湿地区的多种抗病毒和抗锈斑豆种质由普遍定期审议农业试验站，农业研究和林业研究所以及USDA–ARS于2019年合作开发和发布。PR1572-19和PR1572-26都具有bgm-1基因，可抵抗BGYMV，I和bc-3在美国和加勒比海地区对所有BCMV和BCMNV菌株具有广泛抗性的基因座，以及对所有已知的锈病病原种都具有综合抗性的Ur-3和Ur-11基因座。PR1572-26还具有与BGYMV抗性相关的SW12定量性状基因座标记。在波多黎各进行的试验中，PR1572-1-19和PR1572-26产生的平均种子产量与普通品种“圣达菲”相似，而在波多黎各进行的合作式干豆苗圃中，平均种子产量与普通品种“拉巴斯”相当。对于杜兰戈人种的普通豆（包括斑豆和北方市场大类），这两条线都可以作为抵抗BGYMV，BCMV，BCMNV和豆锈的有用来源。
