| Abstract: | From 1982-1984,we identified 25 rice-strains in five natural disease plots in different counties,we have found that strain 15(multi N-2)and strain 20 with higher yield are most resistant to rice blast.Strain 1(791-6-3-3),strain 5(3-37-10-2)and strain 14(multi N-1) give higher yields and are moderately resistant.But further experiments are needed for studying their stability.Strain 11 is supposed to have herizontal resitance.Its horizontal resistance needs to be further identified.
In identifying the resistance of rice to the rice blast,the methods of inoculation should be in combination with the natural infection method.We should especially point out that in identifying the resistance of rice plants to the heavy application of nitrogen and use of cold irrigation water are not necessary. |
