AR1 Disease Resistant

AR1 is resistant to soybean cyst nematode and Phytophthora root rot. The specific resistance to Phytophthora root rot is conferred by the gene Rps1-k which protects the soybean from numerous Phtytophthora root rot races present in the state of Iowa. Rps1-k provides resistance to Races 1-11, 13-15, 17, 18, 21-22, 24, and 26. It is also resistant to SCN phenotypic Race 3 (H.G. Type 0) and moderately resistant to Race 4 (H.G. Type 2.5.7). AR1 has purple flowers, tawny pubescence, tan pods at maturity, and seeds with black hila in its majority ( 95% black hila and 5% brown hila) and dull seed coat.

Resistance of AR1 to Phytophthora root rot and to SCN has been extensively evaluated and confirmed by different means, i.e. greenhouse inoculations for Phytophthora root rot. For SCN, plantings on SCN-infested soil were conducted to determine the H.G. type, and molecular analysis has been done to determine QTL associated with SCN resistance. It possesses QTL N, as determined by molecular analysis which is different from the Peking allele that also confers resistance to SCN.

It is a Maturity Group II. AR1 has adequate yield and it is adapted to environmental conditions in the state of Iowa and other states in which soybeans of MG II are planted. Because of its dual-disease resistance (SCN and Phytophthora root rot) and its adequate seed yield, it may be used in breeding to develop SCN- and Phythophthora root rot-resistant soybean lines with improved yield potential.

If you are interested in obtaining seed of this line, packets of 50 seeds will be available for $200.00 and distributed on a first come basis for research and crossing. A license agreement must be signed with the Iowa State University Research Foundation Inc. and payment must be received prior to receiving seed.

AR2 Fe-efficient

AR2 and AR3 are soybean germplasm lines which are highly Fe-efficient when planted on calcareous soils in Iowa. The Fe-efficiency score has been proven to be associated with molecular marker Satt481 that may be used in further breeding efforts as a molecular marker. The lines may be used in breeding to develop IDC-resistant lines with improved yield potential. AR2 is of Maturity Group II, similar in maturity to Century 84, and AR3 is eight days earlier than Century84
