South Dakota State University (SDSU) has released soybean germplasm lines to help plant breeders elsewhere incorporate desirable qualities such as high protein and low linolenic acid into their own soybean varieties. This is the first time SDSU’s Soybean Breeding and Genetics Program has released soybean germplasm lines. Normally the SDSU program releases soybean varieties suited to conditions in South Dakota and neighboring states.
The new germplasm lines will be available to both public and private sector breeders, as well as soybean researchers. SD00-1501 is a high-protein and high-meal conventional line with acceptable yield and oil content. The protein content at 13 percent moisture average 39.5 to 43.4 percent and average protein meal was 51.5 percent. Oil content was 16.3 to 16.7 percent. Average yield was 39 to 44 bushels an acre. Though the germplasm line is intended mainly for plant breeders and researchers, the line could be grown by producers growing soybeans for certain markets such as the organic sector, tofu, or soy milk.
SD05-767 is a low-linolenic and good-quality conventional line with acceptable yield. Linolenic acid is consistently lower than 3 percent, with an average of 2.6 to 2.8 percent. It also has good protein (37.2 to 40.1 percent) and oil content (17.5 to 18.2 percent) at 13 percent moisture. Yield averaged 40.5 to 46 bushels. The line can also be grown to meet specific requirements for low-linolenic oil.
