Merr. | Iowa, United States | SOY | | Not Available | 2017 | DEVELOPED | | | | | | Breeding material | Soybean yields will be protected by introgressing pathogen-resistance, an objective of soybean breeding for pathogen resistance at Iowa State University (ISU). Germplasms AR4SCN (Reg. No. ), AR5SCN (Reg. No. ), AR6SCN (Reg. No. ), AR7SCN (Reg. No. ), and AR8SCN (Reg. No. ), are resistant to soybean cyst nematode (SCN) HG type 0 (Race 3), and HG type 1.3.6.7 (Race 14). In 2007, ISU Projects 3722- Agronomy, and 3384-Plant Pathology Departments, the Iowa Agricultural and Home Economics Experiment Station (IAHEES), and the ISU Research Foundation (ISURF) released the lines. Each line is a F 12: 13 bulk of 60 agronomical uniform plants from the cross of the genetically diverse SCN parents Pl 88788 and 'Columbia'. The cross made at the lsabela Substation, Puerto Rico, underwent generation advances in PR, and IA. Phenotyping/molecular characterizations of lines at Arelli's, Cianzio's and Diers's labs confirmed the presence of high copy numbers of the full length sequence repeat of the highly important major Pl 88788-type rhg1-b gene, conferring high levels of SCN resistance on each germplasm. In IA, average seed yield of the maturity group (MG) II line AR4SCN was 57% of the 'Dwight' check. For MG Ill lines (ARSCN5, ARSCN6, ARSCN7, ARSCN8), yield was 77% of 'Macon'. The germplasms will serve in the development of SCN-resistant genotypes adapted to northern US regions where SCN HG type 0 and/or 1.3.6.7 may be prevalent. Lines may also serve as research genetic stocks. | 1953971 | PI 684651 |
