Registration of Great Northern common bean cultivar "Panhandle Pride" with enhanced disease resistance to bean rust and common bacterial blight. Journal of Plant Registrations. https://doi.org/10.3198/jpr2019.02.0006crc.
Interpretive Summary: Diseases reduce yields of dry beans, increase production costs, and reduce the quality of pods and seeds. The great northern common bean cultivar Panhandle Pride was developed by the University of Nebraska Agricultural Research Division in collaboration with the Soybean Genomics and Improvement Laboratory of USDA-ARS. Panhandle Pride was bred specifically for adaptation to the western Nebraska growing conditions. Nebraska leads all states in the U.S. in production of the Great Northern market-class of dry beans. Panhandle Pride was also developed for enhanced resistance to bean rust, common bacterial blight (CBB), and bean common mosaic virus (BCMV). CBB and BCMV are caused by seed-borne bacterial and viral pathogens respectively, while bean rust is caused by a fungus dispersed by wind. All three diseases are recurrent east of the Rocky Mountains where at least 80% of U.S. bean production occurs. Panhandle Pride was significantly more resistant to CBB than the popular great northern cultivar Orion. This research describes the genetics of Panhandle Pride and describes the release of the germplasm to growers. Panhandle Pride will be useful to bean growers who would like to reduce yield losses to CBB, BCMV, and rust.
Technical Abstract: Great northern common bean (Phaseolus vulgaris L.) cultivar 'Panhandle Pride' (Reg. No.CV-, PI) was developed by the dry bean breeding program at the University of Nebraska Agricultural Research Division and released in 2016. It was bred specifically for adaptation to western Nebraska growing conditions and for enhanced resistance to bean rust Uromyces appendiculatus (Pers.:Pers) Unger, and common bacterial blight (CBB), a major disease of common bean caused by the seed borne bacterium Xanthomonas axanopodis pv. phaseoli (Smith) Vauterin et al.. Panhandle Pride is a great northern F7:12 line derived from a modified double cross ABC-Weihing/// G95023/Weihing//BelMiNeb-RMR-11. The first cross was made in the winter of 2006. The F7:12 was tested in 12 advanced yield trials at Scottsbluff and Mitchell, NE, and in 16 growers' fields in Nebraska since 2011. Yield of Panhandle Pride was only 100 and 24 kg ha-1 lower than Marquis and Orion, respectively, but higher than Aries, Coyne, and Beryl-R by 440, 329, and 51 kg ha-1, respectively, in Morrill and Scotts Bluff, counties, NE. The reaction of Panhandle Pride to the CBB pathogen under field conditions was consistent across three years at the West Central Research and Extension Center, North Platte, NE where disease ratings of 6.0, 4.3, and 5.2 were recorded in 2011, 2013, and 2014, respectively. Panhandle Pride has the Ur-3 and Ur-6 genes for resistance to bean rust and carries the single dominant hypersensitive I gene that provides resistance to all non-necrotic strains of the bean common mosaic virus (BCMV). Panhandle Pride carries the SCAR markers SAP6 and SU91 linked with a major CBB resistance QTL, the SS68 KASP linked with the Ur3 bean rust resistance locus, and the SW13 SCAR marker linked with the I gene for resistance to BCMV. Panhandle Pride has bright white seed, blooms 44 days after planting, and is a midseason bean, maturing 87 days after planting.
