Narrative
DS13-141 is an improved early MG IV soybean germplasm with indeterminate stem termination, purple flowers, tawny pubescence, brown pods, brown hila, and yellow seed coats. Plants of DS13-141 are 79 cm tall and have a 1.1 lodging score (1-5 scale). Seeds weigh 14.2 g/100 seeds and were 37.1% protein and 18.6% oil (13% moisture). DS13-141 has partial resistance (Red Brown reaction) to 15 soybean rust (Phakopsora pachyrhizi) isolates (AL04-1, AL04-3, AU79-1, BZ01-1, BZ01-2, CO04-2, HW98-1, IN73-1, LA04-1, PG01-2, SA01-1, TW80-2, TH02-1, ZM01-1, and MS06-1b) and TAN (susceptible) reactions to PH77-1 and TW72-1. This differential reaction of DS13-141 to the 17 isolates was unique, indicating its unique mode of resistance to soybean rust. DS13-141 had 22% yield loss under heavy soybean rust pressure in Paraguay, whereas L87-0482 (Rpp4) suffered 31% yield loss and susceptible S07-5049 suffered 38% yield reduction. DS13-141 has resistance to stem canker (Diaporthe aspalathi) and to Phytophthora root and stem rot (Phytophthora sojae) races 1, 3, 7, and 17, but mixed reactions to races 4 and 25.
