Dry Bean Breeding Program
April 06, 2006

Project Leader: Dr. Kenneth Grafton

Research Associate: Dr. Jean R. Gelin

Research Associate: Dr Gonzalo Rojas-Cifuentes

Research Specialist: Albert J. Vander Wal

 

I - Objectives

The objective of the dry bean breeding program at NDSU is to develop high yielding, high quality bean genotypes adapted to the Northern Great Plains. This  involves many characteristics of dry beans and different disciplines of research (e.g. genetics, pathology, physiology, nutrition etc.). Main effort are in pinto and navy beans, but also blacks, great northerns, reds and kidneys are important part of our program.

 

II - 2005 Research Activities 

Locations and Trials

During 2005 growing season 39 experiments and breeding material were planted at 5 locations in North Dakota, and at 2 locations in Minnesota.

Midwest Regional Performance Nursery (20 lines)

F3 Space Plants (525 rows)

F2 Space Plants (234 rows)

Minnesota Locations and Trials:

Root Rot Study (11 cultivars)

F5 Plant Rows (264 rows)

Perham

Miscellaneous Variety Trial (12 lines)

Root Rot Study (11 cultivars)

F4 Plant Rows (264 rows)

 

Crossing Block

At NDSU greenhouses, 205 crosses were made. Of those 49% were pinto, 23% navy, 14% black and 14% great northern and red beans.

 

Disease Testing

During 2005 1520 line were tested for anthracnose resistance, 100 lines were tested for rust resistance and 100 lines were tested for common bean mosaic virus.

         

Cooperation Studies

Root rot study was conducted at Park Rapids and Perham in Minnesota in collaboration with Drs. Rasmussen and Bradley, Plant Pathology Department at NDSU.

A population is being developed for white mold resistance for further screening for Dr. Rasmussen. A small trial was maintained in Park Rapids, MN in collaboration with Dr. Peter Graham, Soils Science Department, University of Minnesota, to develop lines with high nitrogen fixing abilities.

 

Winter Nurseries

280 F1 lines were sent to our winter nurseries in New Zealand. 580 F4 selections from F3 space plants (pinto, navy, great northern, red, and black beans), 238 F3 selections from F2 space plants (navy and black beans), 40 F5 selections from f4 plant rows and 17 F6 selections from F5 plant rows (kidney beans) were sent to our nursery in  Puerto Rico.

 

DNA markers

Microsatelitte markers were used to screen a navy bean recombinant inbred line population for association with seed-micronutrient accumulation. This population was developed for the cross Albion/Voyager. Screening of the AN population that segregates for white mold resistance is underway.

 

III  Results 

A total of 2500 test plots of advanced and preliminary yield trials were harvested. In advanced yield trials 44 pinto, 47 navy, 24 black and 14 great northern and red bean lines were tested.

For the variety trials 372 plots for the. Pinto, Navy, Miscellaneous and Kidney.

More than 4000 single plant selections from breeding trials were made and harvested. Due to wet conditions we were not able to plant approximately 20 acres of early generation trials, in which more selections would have been made.

 

After many evaluations in several trials in and out of North Dakota about 3-4 experimental lines will be considered for pre-release in the near future.

 

Microsatellite markers associated with accumulation of zinc, phosphorus, and calcium in the bean seed were identified. Further evaluation is needed before possible application in marker-assisted selection for these traits.
