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 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 or more...

Information And Results
Project Deliverables

The winter nursery activities are an integral part of the soybean breeding and genetics program. New varieties and germplasm lines will be released for research and commercial use. Information from basic research, thesis studies, variety development, and performance data will be published in extension and scientific journals where appropriate.

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.
