The CIAT rice breeding program has been developing germplasm resistant to P. oryzae since 1967. The distribution of these lines throughout Latin America is done using the observational nursery (VIOAL) organized by the International Network for Genetic Evaluation of Rice-INGER. Augmented design wi...

Thirty-four fungicides were applied to soil at the time the blast susceptible Fanny rice variety was planted in 1 m(2) plots, replicated twice. On the basis of blast incidence and spike development the most effective fungicides were Benlate, NF.44, Duter, Brestan and Desmosan

Sixty rice cultivars were planted in 20 m long plant beds 1.20 m wide at two locations: Meta Department where good temperature and humidity conditions exist for blast (Pyricularia oryzae) development, and Cauca Valley where temperature is near optimum but humidity is low. At the Cauca location th...

The infection efficiency and the infection rate of the spore population of Pyricularia oryzae was lower if the percentage of races to which each cultivar was resistant was high. It appears that cultivars with resistance to a high percentage of the races of the pathogen behaved as expected for “ho...


Sang Won AhnOu, SH[Epidemiological implications of the spectrum of resistance to rice blast]Epidemiological implications of the spectrum of resistance to rice blast

Eighteen rice cultivars used for differentiating physiologic races of Pyricularia oryzae in the Philippines were repeatedly exposed in the blast nursery, and seven of them artificially inoculated with 40 single-spore isolates. The number of lesions that formed on individual cultivars was negative...
