Brief Project Summary:

We intend to use a marker-facilitated, fast-track, backcrossing scheme to create BNF- and BNF+ activity contrasts as two near-isogenic lines in five different high-yielding contemporary soybean backgrounds - one in each of five maturity groups 0, I, II, III, and IV. The lines can be used in NE and in the other 12 States of the NCSRP for research aimed at better understanding relationships between soybean yield potential and N-uptake by soybean plants. This project will provide genetic tools to better characterize the apparent decline in harvest index and in seed yield estimates at high-BNF activity. These tools will be made available to the research community upon completion of this project....

Project Deliverables

This is a 3-year project from Oct 1, 2019 through Sep 30, 2022.
After the creation of the five high yield variety Rj1Rj1 and rj1rj1 NIL pairs, the PIs will work with breeders, physiologists, and agronomists in NE and the north central region to conduct multi- site tests to evaluate the impact of the paired NILs of BNF+ and BNF- in one or more of the five MG- varieties that can be grown in each state. Seed will be available after a seed increase of the NIL pairs during 2022. The PIs will work with researchers in the 12-state NCSRP to prepare a research proposal using the NILs in soybean-related N research for submission to the NCSRP in the spring of 2022.

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.
