Davis M, Rott P, Warmuth C, Chatenet M, Baudin P (1997) Intraspecific genomic variation within Xanthomonas albilineans, the sugarcane
leaf scald pathogen.
In the USA,
leaf scald is a serious disease of barley in the Pacific Northwest, California, and the Mid Atlantic region, where yield losses can reach 40% (Mathre, 1997).
The sugarcane (Saccharum officinarum L.) resistance to
leaf scald has been studied without consideration of the percentage of damage to the vascular system.
spontaneum have been identified that carry resistance to powdery mildew (Jahoor and Fischbeck, 1987a, 1987b), NTNB (Sato and Takeda, 1997), SSLB (Fetch et al., 2003; Metcalfe et al., 1977, 1978), and
leaf scald (Genger et al., 2003).
Since the first variety programs started there over 70 years ago, ARS scientists and collaborating university researchers have supplied industry with 86 varieties of high-yielding sugarcane, most armed with resistance to yield-reducing diseases like sugarcane mosaic virus, eye spot, smut, rust, ratoon stunting,
leaf scald, and, more recently, insect pests like sugarcane borers.
CP 97-1944 is susceptible to Sugarcane yellow leaf virus, and is moderately susceptible to
leaf scald [caused by Xanthomonas albilineans (Ashby) Dowson] and ratoon stunting disease (caused by Leifsonia xyli subsp, xyli Evtushenko et al.).
CP 97-1989 is moderately susceptible to
leaf scald [caused by Xanthomonas albilineans (Ashby) Dowson] and ratoon stunting disease (caused by Leifsonia xyli subsp, xyli Evtushenko et al.), and CP 97-1989 is susceptible to Sugarcane yellow leaf virus.
