PR0806‐80 (Reg. No. GP‐296, PI 672994) and PR0806‐81 (Reg. No. GP‐297, PI 672995) are multiple disease‐resistant dry bean ( Phaseolus vulgaris L.) germplasm lines adapted to the humid tropics, developed and released cooperatively by the University of Puerto Rico Agricultural Experiment Station, the USDA–ARS, the Escuela Agrícola Panamericana (Zamorano), the Instituto Dominicano de Investigaciones Agropecuarias y Forestales, and the Ministry of Agriculture, Natural Resources and Rural Development of the Republic of Haiti. The breeding objective was to develop white dry bean lines that combine resistance to Bean common mosaic virus (BCMV), Bean common mosaic necrotic virus (BCMNV), Bean golden yellow mosaic virus (BGYMV), and rust, caused by Uromyces appendiculatus (Pers.) Unger. PR0806‐80 and PR0806‐81 were developed by pedigree selection to the F 6 generation on the basis of superior agronomic traits, disease resistance, and commercial seed type. Advanced generation lines were screened for rust resistance in Honduras and were resistant to BGYMV, BCMNV, and rust in trials planted in Puerto Rico, the Dominican Republic, and Haiti. Results from greenhouse inoculations suggest that the lines combine the Ur‐4 , Ur‐5 , and Ur‐11 alleles of rust resistance genes. Greenhouse inoculations were used to detect the presence of the bc‐3 gene for resistance to BCMV and BCMNV, and marker‐assisted selection was used to identify the presence of the bgm‐1 allele and the SW12 quantitative trait locus for BGYMV resistance. The presence of SA14 and SI19 sequence characterized amplified region (SCAR) markers provided further evidence that these lines have the rust resistance genes Ur‐4 and Ur‐5 . The lines were evaluated in field trials in the Dominican Republic, Haiti, and Puerto Rico. Mean seed yields of PR0806‐80 (2048 kg ha −1 ) and PR0806‐81 (2091 kg ha −1 ) were comparable to the check cultivar ‘Verano’ (2251 kg ha −1 ). These multiple disease‐resistant white lines should be useful as parents to enhance the virus and rust resistance of white, small red, and black beans.
