Retired Cereal Disease Laboratory research plant pathologist Alan Roelfs was recently recognized for his dedicated contribution to the study of rust on wheat and his training and mentoring of students by the release of a new cultivar, Roelfs F2007, at a ceremony in April at Obregon, Mexico in partnership with the the Agricultural Research and Experiment Trust of the State of Sonora (PIEAES)  and the International Maize and Wheat Improvement Center (CIMMYT). 

Dignitaries from CIMMYT, PIAEAS, CIRNO, INIFAP, Fundacion Produce Sonora, and the undersecretary of Agriculture of Sonora were on hand for the dedication which was widely covered by the press and media. 

Roelfs F2007 is the result of the  cross Kamba1*2/Kukuna.  The new bread wheat is higher yielding, has adult plant (slow rusting) resistance to leaf rust and stripe (yellow) rust (Lr34, Yr18  along with several minor additive genes) and good quality characteristics.

Alan was unaware when he accepted the gracious invitation to visit the area that he was to be honored with the release of a variety in his name and was nearly speechless at the tribute.

“It’s a great honor.  I’ve worked with researchers from INIFAP, and also visited CIMMYT on various occasions to attend meetings, offer information, ask questions, and listen to what they propose, and with all that you form an image of the problem and possible solutions for which I am very grateful” Roelfs said in an interview.
