Brief Project Summary:

The winter nurseries allow for continuous operations and progress in the breeding program year-round. At the two Chile nurseries we evaluate 10,000 to 15,000 progeny rows each winter, grow and harvest 5,000 to 8,000 individual plants from 20 or more new populations to go into progeny row evaluations in Nebraska, and conduct yield tests on high-yielding advanced lines from our program under specific water treatments important for soybean production in Nebraska. At the Puerto Rico nursery we advance over 200 populations for two generations between October and May, conduct our main crossing for new research and variety development for all objectives under the lighted area, and evaluate 4,000...

Information And Results
Project Deliverables

(1) Conduct generation advance for soybean breeding and genetics studies to obtain 2 additional generations per year
(2) Crossing for development of new populations for breeding and genetics objectives
(3) Evaluate progeny rows for selection and advancement to multi-location yield tests
(4) Conduct small-scale seed increases of specific lines for research studies and for specific lines to hasten development and commercial production when appropriate.

Final Project Results

We continue to make steady and significant progress in yield and compositional quality in our breeding program. The winter nurseries are integral to that success. With the Puerto Rico and Chile nurseries, in one year we obtain an additional crossing season, two additional generation advance seasons, and another yield test and progeny row evaluation season for all of our objectives. The impact is shown in our continued outputs of high-yielding soybean cultivars well adapted to Nebraska production environments and the north central US.

The United Soybean Research Retention policy will display final reports with the project once completed but working files will be purged after three years. And financial information after seven years. All pertinent information is in the final report or if you want more information, please contact the project lead at your state soybean organization or principal investigator listed on the project.
