This study was carried out in Suwon-central plain, and Cheorwon, mid-northern plain of Korea to evaluate agricultural characteristics including heading date and yield component for North Korean rice germplasm. The difference between two regions of the heading dates of germplasm was recognized the significance and early matured group growing in Cheorwon tended to flower earlier than that of Suwon while mid-early matured group showed an opposite result. The other agricultural characteristics such as culm length, panicle length, number of panicles per hill, number of grains per panicle, and ripened grain ratio, of the two regions of all traits were highly significant, especially culm length and panicle length in Suwon were longer than those were growing in Cheorwon. Number of panicles per hill and number of grains per panicle in Suwon were more than that were growing in Cheorwon, and ripened grain ratio in Suwon was higher than that of Cheorwon. The another difference between both the regions, of 1000-grain weight was not significant while the effect of interaction between the regions and variety was highly significant. Whereas brown/rough rice ratio and milled rice yield were highly significant; higher in Cheorwon for brown/rough rice ratio and in Suwon of milled rice yield. Additionally, the results concluded that, the North Korean rice germplasm showed susceptible response to bacterial leaf blight(BLB) races such as K2. K3, and K3a but more than mid-range resistant response to rice blast.
