| 0 | PI 705143 | 'R18-14147' | Glycine max (L.) Merr. | Arkansas, United States | SOY | | Not Available | 2024 | DEVELOPED | | | | | | | R18-14147 is a high-protein conventional soybean germplasm of maturity group Mid-IV developed and released by the University of Arkansas System – Division of Agriculture Research & Extension in 2023. The germplasm is an F3:4 selection from the cross LG10-3671-1 × R09-430. Plants of R18-14147 have an indeterminate growth habit with purple flowers, gray pubescence, brown pod wall, and imperfect black hilum. Across 28 environments in Arkansas (2019-2022), R18-14147 yield averaged 4482 kg ha-1 with broad adaptability and yield stability. Seeds of R18-14147 contain an average of 429 g kg-1 and 191 g kg-1 of protein and oil on a dry weight basis, respectively, and weigh 15.2 g 100 seeds-1. The average seed protein content of this line is 8 to 27% higher than the average protein content of the check cultivars used in various trials to evaluate R18-14147. Additionally, R18-14147 has been identified as resistant to stem canker caused by Diaporthe phaseolorum var. aspalathi. R18-14147 presents soybean growers in the mid-South US with a promising germplasm alternative combining high-yield potential and elevated seed protein content for alternative crop rotation in herbicide-tolerant cultivar systems, offering potentially seed-saving cost benefits and serving as a valuable germplasm for new cultivar development | 2166528 | PI 705143 |
