DENNISON (formerly HSl-3717 and OHS 301) is a 2006 release of The Ohio State University. Dennison is a unique conventional variety because of its combination of resistance genes (Rps1k andRps3a) and excellent partial resistance to Phytophthora root rot in a genetic background with high yield.This new variety resembles Kottman in appearance and is a replacement for Kottman and Resnik.This soybean variety is a 3.5 maturity, with black hilum, tan pods, light tawny pubescence and white flowers, with up to .3% purple flowers allowed.
CLERMONT (formerly HS7-4314; tested as Highland) is a 2012 soybean release of The Ohio State University. Clermont is a conventional soybean variety being released due to its excellent yields and race-specific resistance to Phytophthora sojae. Field evaluations for Frogeye leaf spot also indicated a lack of leaf lesions. Clermont’s relative maturity is 3.9 and it matures approximately four days later then “Dennison”. The average height of this variety is 96 cm. The variety has white flowers,light tawny pubescence, brown pods, dull yellow seed coat, black hilum color, and indeterminate growth habit.
LORAIN (formerly HS7W-82) is a 2014 soybean release of the Ohio State University. Lorain is a conventional soybean variety being released due to its excellent yields and race-specific resistance Rps1c to Phytophthora sojae. Based on a single green house assay, Lorain is moderately susceptible to Sudden Death Syndrome (SDS). Root rot scores indicated that Lorain has high levels of partial resistance which are similar to Dennison. Lorain is a 3.4 maturity variety with white flowers, light tawny pubescence, dull yellow seed coat, black hilum and indeterminate growth habit.
RESNIK is a high yielding variety from the soybean breeding program at the Ohio Agricultural Research and Development Center released in 1982. The variety carries the Rps1k gene which confers resistance to races 1-10, 13-15, 17, 18, 21 and 22 of Phytophthora root rot. Resnik has shown superior yield potential in pre-release testing in Ohio and regional trials. Resnik is a mid Group III in maturity, about 4 to 6 days earlier than Williams 82. Resnik exhibits purple flowers, brown pubescence and tan pods at maturity and has yellow seeds with a dull luster and black hila.
STREETER is an early Group 3.0 maturing conventional soybean variety released by The Ohio State University in 2008. It is approximately one day later in maturity than Wyandot, but yields higher than Wyandot and is two inches taller. Streeter has excellent lodging resistance. The variety has white flowers, light tawny pubescence, tan pods and black hilum color. This line carriers Rps1c and Rps3a for Phytophthora resistance.
SUMMIT is a high yielding conventional oil and meal type soybean variety released by The Ohio State University in 2011. The variety has a 2.6 relative maturity, purple flowers, light tawny pubescence, tan pods and a black hilum. Based on preliminary data “Summit” has multiple Rps genes and a high level of partial resistance to P. sojae.
WYANDOT 14 is a 2012 release of the Ohio State University (OSU). This variety has a very good yield record and serves as a replacement for Wyandot. Resistance to Phytophthora is realized with the presence of the Rps3a gene. This 2.9 maturity variety has white flowers, gray pubescence, brown pods and yellow (clear) hila. Wyandot 14 is specially adapted to the northern half of Ohio soybean growing regions, where soybean aphid and powdery mildew are likely pests. In six different yield environments over a three year period Wyandot 14 had higher or equal seed yields compared to Wyandot. Seed size, seed protein and seed oil content is similar to Wyandot. This variety has indeterminate growth habit and equal or superior agronomic attributes than Wyandot.
IA 3051RA12 has a maturity rating of 3.1 and was released by Iowa State University Research Foundation. It was developed by backcrossing the Rag1 and Rag2 alleles into IA3051. IA3051RA12 has white flowers, brown pods, gray pubescence and seeds with yellow hila and yellow seed coat color. There are variants for up to 1% purple flower color and up to 1% tawny pubescence. Recognized classes are F, R and C.
