Stampede, an upright pinto bean
variety for use in the northern Great Plains, has been released
by the North Dakota Agricultural Experiment Station at
North Dakota State
University.
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
According to Juan Osorno, NDSU dry edible bean breeder in the
Department of Plant Sciences, Stampeded was developed under the
supervision of Ken Grafton, former NDSU dry bean breeder and now
dean of the College of Agriculture, Food Systems, and Natural
Resources and director of the North Dakota Agricultural
Experiment Station.
The NDSU Research Foundation will apply for plant variety
protection with Title V and collect research fees on this
variety. |
