Registration Of 'Highpro1' Soybean With High Protein And High Yield Developed From A North X South Cross
JOURNAL OF PLANT REGISTRATIONS(2017)
摘要
'Highpro1' soybean [Glycine max (L.) Merr.]) (Reg. No. CV-521, PI 678444) was developed and jointly released by the USDA Agricultural Research Service and The Ohio Agricultural Research and Development Center in Wooster, OH, as a high-protein high-yielding maturity group (MG) III (relative maturity 3.7) conventional soybean cultivar. Highpro1 is a selection from a cross between a food-grade soybean cultivar, 'Wyandot', from The Ohio State University and a high-protein breeding line, GASF98-114, from University of Georgia Athens. Across 20 environments in the Northern Regional Soybean MG-III Quality Traits Tests, Highpro1 yielded (3746 kg ha(-1)) the same as the mean yield of four high-yielding check cultivars in the tests, and its protein content was much higher than the checks. On a 13% (w/w) moisture basis, Highpro1 produced 401 g kg(-1) seed protein compared with the check cultivars' averages of 344 g kg(-1) seed protein. Across five environments of yield testing in Ohio, this line produced 4% higher seed yield and 45 g kg(-1) higher seed protein content than the early-maturing parental cultivar Wyandot. However, it is 7 d later in maturity with 18 g kg(-1) lower seed oil content than Wyandot. In 2012 Ohio State Soybean Performance Trials, seed yields of Highpro1 were comparable to the yields of high-yield check cultivars of similar maturity and 10% higher than that of Wyandot. Highpro1 is resistant to southern root knot nematode, and it has high level of partial resistance to Phytophthora root and stem rot.
