'Stampede' Pinto Bean (RFP-157)
'Stampede' is an upright pinto bean variety for use in the northern Great Plains.
Averaged across numerous locations during several years of testing, 'Stampede' out-yielded 'Maverick' by more than 11 percent. 'Stampede’s yield is about equal to 'Buster' and has a slightly larger seed size than 'Maverick'. 'Stampede' has resistance to bean common mosaic virus and local races of leaf rust.
'Stampede' has an upright, short vine with good lodging resistance. It exhibits very uniform dry down of both pods and plants and matures about one day later than 'Maverick'. The improved plant structure, combined with its uniform dry down, suggests that this line may be suitable for direct combining if the appropriate equipment and operator care are used.
The development of 'Stampede' began in 1996. The parentage of 'Stampede' includes numerous experimental lines from the NDSU breeding program, plus germplasm from the USDA-ARS programs at Beltsville, Md.; Mayaguez, Puerto Rico; Michigan State University; and Colorado State University. The final cross that led to the development of 'Stampede' was made during the greenhouse season in fall 1998. Plants resulting from this cross then were increased and tested in New Zealand and Puerto Rico, where the NDSU dry bean breeding project has winter nurseries.
Selections from the cross were made at the NDSU bean breeding nursery in Hatton, N.D. Additional testing, selections and increases were made at numerous sites in east-central North Dakota (Forest River, Johnstown and the Carrington Research Extension Center). Additional evaluations were done at other NDSU Research Extension Centers and in the Midwest Regional Performance Nurseries in Michigan, Nebraska, Colorado and North Dakota.
The NDSU Research Foundation holds plant variety protection (certificate no. 200800304) on 'Stampede' and collects research fees on this variety.
