Select the tab for the type of search. Each tab has everything you need to do to perform that type of search.

(Results of more than 500 will not return images.)

This search will show only accessions that have material that may be requested, including those not seasonally available.
You may list accessions with separators (commas or semicolons, as shown below) or by entering them on separate lines, such as
PI 651794
PI 651649
PI 651650
When searching a range of accessions, use the Advanced Search tab with the Accession Identifier Range criterion.

The more information you provide, the better the search will be.

0PI 672994'PR0806-80'Phaseolus vulgaris L. Puerto Rico, United StatesW62014DEVELOPEDBreeding materialPR0806-80 and PR0806-81 are multiple disease resistant dry bean (Phaseolus vulgaris L.) germplasm lines, adapted to the humid tropics, that were developed and released cooperatively by the University of Puerto Rico Agricultural Experiment Station, the USDA-ARS, the Escuela Agricola Panamericana (Zamorano), the lnstituto Dominicano de lnvestigaciones Agropecuarias y Forestales and the Ministry of Agriculture, Natural Resources and Rural Development of the Republic of Haiti. PR0806-80 and PR0806-81 were developed by pedigree selection to the F6 generation based on superior agronomic traits 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 with specific strains of bean rust at USDA-ARS-Beltsville suggest that the lines combine the Ur-4, Ur -5, Ur-11 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 gene and the SW12 QTL for BGYMV resistance. The presence of SA14 and Sl19 SCAR markers provided further evidence that these lines have the rust resistance genes Ur-4 and Ur-5. These multiple disease resistant white lines should be useful as parents to enhance the virus resistance of white, small red and black beans.1920911PI 672994
