IA2068

IA2068 has seeds with yellow hilum color and dull seed coat luster, which makes it desirable for production of either commodity or food-grade soybeans. 

IA2068 has resistance to the soybean cyst nematode (SCN).  Reproduction of cysts on the variety was evaluated in three soil types by Dr. Terry Niblack of the University of Illinois.  Its resistance was compared with other public and private varieties and brands in the 2003 Iowa Crop Performance test conducted by the Iowa Crop Improvement Association and Iowa State University.  For the complete table, go to www.agron.iastate.edu/icia   IA2068 was in the top group of entries for SCN resistance. 

IA2068 yields very well on SCN-infested soils.  It is recommended that growers rotate resistant varieties on SCN-infested soils.  For producers of food-grade soybeans with a yellow hilum color, IA2068 will serve as a good alternative to IA1008, a variety with yellow hilum color and resistance to SCN.  The two varieties have had similar yields on unifested soils during three years in the Iowa Specialty Soybean Test.

IA3014 is an F4 plant selection from the cross LN90-4366 x IA3005. LN90-4366 is a line from the University of Illinois that was selected from the cross LN86-4668 x Resnik. IA3005 is a variety developed by Iowa State University that has soybean cyst nematode (SCN)resistance. It was selected from the cross LS82C-1212 x Kenwood.

IA3014 has white flowers, tawny pubescence, brown pods at maturity, and seeds with black hila and dull seed coats.

IA3023

IA3023 was the highest yielding public variety or experimental line in the 2003 Uniform Regional Test III that was conducted by public soybean breeders in 18 locations in the northern United States. 

IA3023 was compared with other public and private varieties of similar maturity in the 2003 Iowa Crop Performance test conducted by the Iowa Crop Improvement Association and Iowa State University.  For the complete table, go to www.agron.iastate.edu/icia   IA3023 was one of the highest yielding entries of in the test.  It has good emergence and excellent lodging resistance.   IA3023 has seeds with black hilum color and dull seed coat luster.

A95-684043

A95-684043 is an F4 plant selection from the cross Jacques J285 x [Archer x (Cordell x Asgrow A2234)]. Jacques J285 is a high-yielding cultivar developed by Mycogen Seeds, St. Paul, MN, which was selected from the cross Weber X Asgrow A3127. Archer is an iron-chlorosis and BSR-resistant cultivar developed cooperatively by the Iowa Agriculture and Home Economics Experiment Station and the Puerto Rico Agricultural Experiment Station. It was developed by backcrossing the Rps1-k and Rps6 genes for resistance to phytopthora rot into BSR 101. Each gene was transferred independently to BSR 101 with four backcrosses, and the BC4F1 plants from the two backcrossing programs were intercrossed to obtain F1plants with both genes. F4 plants homozygous for both alleles and with similar agronomic characteristics were bulked to form Archer. Cordell is a cultivar resistant to SCN phenotypic races 3,4, and 5 developed from the cross of Bedford x D72-8927, cooperatively by the USDA-ARS with the Delta Branch, Mississippi Agricultural and Forestry Experiment Station and the West Tennessee branch of the Tennessee Agricultural Experiment Station. Asgrow A2234 is a high-yielding cultivar from the Asgrow Seed Co., Kalamazoo, MI , which was selected from the cross [(Calland x Amsoy) x Century] x Williams 82.

A95-684043 has purple flowers, tawny pubescence, brown pods at maturity, seeds with black hila, and dull seed coat.

A95-684043 matures approximately 3 days before IA3010. It is resistant to SCN phenotypic races 1,3, and 5.

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
