Interpretive Summary: "Bella" is a multiple disease resistant white common bean cultivar, adapted to the humid tropics, that was developed and released cooperatively by the University of Puerto Rico Agricultural Experiment Station and the USDA-ARS. The breeding objective was to develop a white dry bean line that combines resistance to viruses, including Bean common mosaic virus (BCMV), Bean common mosaic necrotic virus (BCMNV), Bean golden yellow mosaic virus (BGYMV). In addition it has resistance to a bacterial disease, common bacterial blight and to a fungus, web blight. The line also tolerates high temperatures and performs well in soils with low fertility. PR1217-16 was developed by pedigree selection based on superior agronomic traits and commercial seed type. A laboratory selection approach, molecular marker- assisted selection, was used to identify the presence of the bgm-1 gene and the SW12 QTL for resistance to BGYMV and the I and bc-3 genes for resistance to BCMV and BCMNV. Greenhouse inoculations were used to confirm the presence of the I and bc-3 genes for resistance to BCMV and BCMNV and to screen the line for reaction to strains of common bacterial blight. The line was evaluated in field trials planted over a period of five years in Puerto Rico. Mean seed yields of PR1217-16 were comparable with the check cultivars ‘Verano’, ‘Morales’ and ‘Beníquez’. PR1217-16 produced among the highest yields in the Bean Adaptation to Stress Environments (BASE) 120 trials planted at Isabela and Juana Diaz, Puerto Rico. This multiple disease resistant white bean cultivar should allow the successful production of the crop in Puerto Rico throughout the year in soils with low N fertility. PR1217-16 should also be useful as a parent to enhance the virus, common bacterial blight and web blight resistance of white, small red and black beans.

Technical Abstract: "Bella" Reg. No. GP-___, PI ______) is a multiple disease resistant white bean (Phaseolus vulgaris L.) cultivar, adapted to the humid tropics that was developed and released cooperatively by the University of Puerto Rico Agricultural Experiment Station and the USDA-ARS. The breeding objective was to develop a white dry bean line that combines resistance to Bean common mosaic virus (BCMV), Bean common mosaic necrotic virus (BCMNV), Bean golden yellow mosaic virus (BGYMV), common bacterial blight caused by Xanthomonas axonopodis pv. phaseoli and web blight caused by [Rhizoctonia solani J. G. Kühn (syn. Thanatephorus cucumeris (A. B. Frank) Donk.)]. The line also tolerates high temperatures and performs well in soils with low fertility. PR1217-16 was developed by pedigree selection to the F7 generation based on superior agronomic traits and commercial seed type. Marker- assisted selection was used to identify the presence of the bgm-1 gene and the SW12 QTL for resistance to BGYMV and the I and bc-3 genes for resistance to BCMV and BCMNV. Greenhouse inoculations were used to confirm the presence of the I and bc-3 genes for resistance to BCMV and BCMNV and to screen the line for reaction to strains of common bacterial blight.
