In Memory – Roland F. Line

Roland F. (Rollie) Line, Research Plant Pathologist, US Department of Agriculture, Agricultural Research Service and adjunct professor, Washington State University, passed away in his home at Pullman, WA on June 4, 2017 at the age of 83.  He was born in Winona, MN, on January 11, 1934 and graduated from high school at Cromwell, MN, in 1952. He received his B.S. (1956), M.S. (1959), and Ph.D. (1962) degrees in plant pathology and genetics from the University of Minnesota. As a research associate at the University of Minnesota (1959 to 1963), he was responsible for research on the ecological potential and survival of the stem rust pathogen. He demonstrated that it was possible to create isolates of Puccinia graminis that were more aggressive at low temperatures and that selection for aggressiveness at low temperatures reduced aggressiveness at high temperatures. With coworkers, he showed that new races could arise by sexual and somatic crosses between Puccinia graminis f. sp. tritici and Puccinia graminis f. sp. secalis.  Read more >>
