    Growth and Development Guide for Spring Wheat
    (St. Paul, MN: University of Minnesota Agricultural Extension Service, 1985) Simmons, S.R.; Oelke, E.A.; Anderson, P.M.
    The description of wheat development provided here applies mostly to spring wheat, although the basic development patterns for all cereals are similar. Figure 1 shows major developmental stages in spring wheat and approximate time intervals between them in Minnesota. A difference in maturity may exist among varieties or between seasons.

    Introgression of leaf rust and stripe rust resistance from Sharon goatgrass (Aegilops sharonensis Eig) into bread wheat (Triticum aestivum L.)
    (Genome, 2014) Steffenson, Brian; Millet, E.; Manisterski, J.; Ben-Yehuda, P.; Distelfeld, A.; Deek, J.; Wan, A.; Chen, X.
    Leaf rust and stripe rust are devastating wheat diseases, causing significant yield losses in many regions of the world. The use of resistant varieties is the most efficient way to protect wheat crops from these diseases. Sharon goatgrass (Aegilops sharonensis or AES), which is a diploid wild relative of wheat, exhibits a high frequency of leaf and stripe rust resistance. We used the resistant AES accession TH548 and induced homoeologous recombination by the ph1b allele to obtain resistant wheat recombinant lines carrying AES chromosome segments in the genetic background of the spring wheat cultivar Galil. The gametocidal effect from AES was overcome by using an “anti-gametocidal” wheat mutant. These recombinant lines were found resistant to highly virulent races of the leaf and stripe rust pathogens in Israel and the United States. Molecular DArT analysis of the different recombinant lines revealed different lengths of AES segments on wheat chromosome 6B, which indicates the location of both resistance genes.
