Research Project: Identication and Utilization of Exotic Germplasm to Improve Soybean Productivitiy

Location: Crop Genetics Research Unit

2010 Annual Report


1a.Objectives (from AD-416)
Identify soybean accessions with high seed germinability.


1b.Approach (from AD-416)
Conduct assays with accessions from the USDA soybean germplasm collection in order to identify accessions with high seed germinability.


3.Progress Report

The objectives of this project are to identify and utilize new soybean resources to improve seed quality, germination, and yield under the stressful production conditions of the midsouthern United States. It relates to the National Program for genetic improvement of soybeans by developing and releasing enhanced genetic resources and varieties.

Over 2,200 lines were tested for seed germination and 464 lines were tested for seed vigor. Over 350 breeding lines had germinations of at least 90%, 21 of which had been tested for 5 consecutive years and had at least 90% germination in each year. These 21 breeding lines were tested for yield and then tested for germinability at the normal time of harvest and after delays in harvest of 2 weeks and 4 weeks. Activities for this project were monitored by the ADODR through site visits, written reports, and meetings.
