متن کاملFusarium Levels in Grain Harvested from New Zealand Wheat and Barley Crops in 2000
Samples of grain from 40 New Zealand wheat and barley crops harvested in 2000 were assayed for Fusarium infection. Grain from all crops was infected, and Fusarium incidence ranged from 3 to 52% of grains infected, with a mean of 14%. Incidence of Fusarium was higher in spring wheat than in autumn wheat or spring barley. The highest level of infection (52% grains infected) was found in Otane whe...
متن کاملAssociation Analysis of Stem Rust Resistance in U.S. Winter Wheat
Stem rust has become a renewed threat to global wheat production after the emergence and spread of race TTKSK (also known as Ug99) and related races from Africa. To elucidate U.S. winter wheat resistance genes to stem rust, association mapping was conducted using a panel of 137 lines from cooperative U.S. winter wheat nurseries from 2008 and simple sequence repeat (SSR) and sequence tagged site...
متن کاملRustmicin, a new macrolide antibiotic active against wheat stem rust fungus.
Sir: Stem rust (Puccinia graminis f. sp. tritici) is a serious wheat disease causing decrease of wheat production in many areas of the world1) and has been partially controlled so far by the use of resistant races2), eradication of the alternate host, i.e. barberry3), or by synthetic fungicides4~7) We undertook the screening of new antibiotics active against wheat stem rust fungus using an inhi...
