Ug99 Effectiveness:
-Virulence for the gene is known to occur in other races
-Level of resistance conferred in the field usually inadequate under high disease pressure

---------------------
Sr42 is derived from common wheat germplasm. Recent genetic mapping of Sr42 resulted in identification of closely linked DNA markers on chromosome 6DS (Ghazvini et al. 2012). The similar map position of this gene and SrCad (Heibert et al. 2011) suggests that Sr42 and SrCad may be the same gene. SrCad is deployed in Canadian spring wheat varieties containing the bunt resistance gene Bt10.
