Tainan 5, a high yielding rice variety but susceptible to blast was crossed with a blast resistant variety, Taichung 184, in the spring of 1969, in order to study the reaction of F2 population to rice blast under field condition. Pure stand Tainan 5, Taichung 184, and their mixed variety were also used in comparison with the F2 population in this experiment. Randomized complete block design with two replications was used. In the spring crop of 1970, all experimental materials were transplanted in the field at a spacing of 20cm×25cm with single plant per hill. The plot size was 2×5m^2 and 200 plants were planted in each plot. The amount of nitrogen applied was 280 kg/ha. Types of the leaf blast lesions, percentage of the leaf blast, percentage of neck blast, and the grain yield were recorded and analyzed.
