DOI: https://doi.org/10.1002/plr2.20215 Interpretive Summary: Vegetable soybean also known as edamame are immature soybean seeds consumed as a vegetable or snack. Selection and propagation of large seeded, good tasting edamame has had a long tradition in Asia. To improve the production of vegetable soybean, we made crosses with vegetable soybean varieties and soybean lines (non-vegetable soybean types) that were known to have resistance to two biotic constraints. These crosses and selection of lines produced new vegetable soybean germplasm with resistance to the soybean aphid and Phytophthora root and stem rot. These large seeded, non-GMO soybean lines have a range of maturities that can be used in most vegetable growing regions in the United States. The combined pest resistance and large seed size of these lines developed in a range of maturities will be value to vegetable soybean industry. This information will be useful to breeders, vegetable growers, and vegetable soybean production specialists. Technical Abstract: The Agricultural Research Service of the United States Department of Agriculture announces the release of soybean [Glycine max (L.) Merr.] germplasm lines LB18-58, LB18-65, LB18-45, LB18-49, LB18-52, LB18-57, LB18-67 and LB18-75 in August 2021. These large seeded, non-GMO soybean lines range in maturity from maturity group (MG) 00 through IV. Each line contains a single gene for resistance to soybean aphid [Aphis glycines (Matsumura)] or Phytophthora root and stem rot (PRSR) [Phytophthora sojae (Kaufm. & Gerd.)]. LB18-58 and LB18-49 have resistance to soybean aphid biotype 3 (Rag1) provided by LD06-16721. Soybean aphid resistance to biotype 2 (Rag2) was derived from LD08-12441 or LB18-65. LD08-12582 provided Rag2 resistance for LB18-52 and LB18-57. Williams 82 was the source of the PRSR resistance gene, Rps1k. C. R. Bowen and G. L. Hartman developed these lines at the USDA-ARS Soybean/maize Germplasm, Pathology, and Genetics Research Unit, Urbana, IL. Large seeded culitvars Tohya (MG 00), BeSweet 2001 (MG II), Gardensoy 24 (MG II) and Gardensoy 41 (MG IV) served as recurrent parents with pest resistant donor lines to develop large seeded, pest resistant soybean lines in a range of maturity groups. The combined pest resistance and large seed size, in a range of maturities, will be valuable for breeders developing large seeded pest resistant cultivars. |
