Interpretive Summary: Soil diseases that rot the roots and stems of dry beans and snap beans cause tremendous loss of yield and revenue to producers worldwide. TARS-PT03-1, a small-seeded pinto bean germplasm line, was recently released by the Agricultural Research Service and the University of Tennessee Agricultural Experiment Station as a new source of resistance to soil-borne fungi that cause root rot, including Fusarium solani, and combinations of F. solani, Rhizoctonia solani, and Pythium spp. TARS-PT03-1 also offers good yield potential and moderate resistance to common bacterial blight. It is adapted to both tropical and temperate growing environments and should help breeders develop new cultivars with improved disease resistance and greater yield potential

Technical Abstract: TARS-PT03-1 was developed cooperatively by the USDA-ARS, Agriculture and Agri-Food Canada, and the West Tennessee Experiment Station, and jointly released by the USDA and the Tennessee Agricultural Experiment Station in 2003 as a multiple disease-resistant, small-seeded pinto dry bean (Phaseolus vulgaris L.) germplasm. It is an F5-derived bulk from the cross TARS VCI-4B//Montcalm/MUS-PM-31-F5. TARS-PT03-1 has a vine (type 3) growth habit and matures in approximately 90 days in SW Ontario, Canada. Plant height is approximately 35 cm and seed size is 28 grams/100 seed. The corona area around the hilum is yellow and the seed coat tends to darken with storage. TARS-PT03-1 has similar resistance to Fusarium solani (Mart.) Sacc. f. sp. phaseoli (Burkholder) W.C. Synder and H. N. Hans. as highly resistant Cornell 2114-12. It has similar resistance as Cornell 2114-12 to mixtures of F. solani, Rhizoctonia solani (Kühn), and Pythium spp. and R. solani, Macrophomina phaseolina (Tassi) Goidanich, and F. solani, but is less resistant than Cornell 2114-12 to a mixture of F. solani, R. solani, and P. ultimum (Trow.). TARS-PT03-1 has intermediate resistance to Xanthomonas campestris pv. phaseoli (Smith) Dye and very good yield potential in both tropical and temperate environments. TARS-PT03-1 is a new and unique source of resistance to soil pathogenic fungi and will be useful for improving resistance to soil pathogenic fungi in dry edible bean and snap bean.
