Registration of soybean germplasm line R14‐1422 with high yield and moderate resistance to southern root knot nematode.

R14‐1422 (Reg. no. GP‐523, PI 702562) is a mid‐maturity group (MG) V (relative maturity 5.4), determinate growth habit, high‐yielding, conventional soybean [Glycine max (L.) Merr.] germplasm line developed and released in 2021 by the Arkansas Agricultural Experiment Station. R14‐1422 is an F4 selection from the cross between 'R06‐4433', a cultivar released by Arkansas, and the Missouri cultivar 'S05‐11482'. Trial results of over 74 environments in Arkansas and other southern states showed that R14‐1422 is well adapted and provides high‐yielding performance. R14‐1422 is a MG V (5.4), line with determinate growth habit, white flowers, gray pubescence, and a tan pod wall at maturity. Seed of R14‐1422 has yellow cotyledon, yellow seed coat, and buff hilum color. R14‐1422 has high yield potential and moderate resistance to southern root‐knot nematode and is a chloride excluder. Core Ideas: R14‐1422 is a new conventional MG 5.4 soybean germplasm line.R14‐1422 has moderate resistance to southern root knot nematode.R14‐1422 is a chloride excluder. [ABSTRACT FROM AUTHOR]
