Abstract: A strong restoring line, Fuhui 636, was developed by crossing Minghui 63 and indica-japonica intermediate type material, 8L124. After years of verification, evaluation, and selection on the blast-resistance of its offspring, a new two-line indica hybrid rice variety, Juliangyou 636, was bred by crossing it with two-line sterile line, RGD-7S. The new variety showed desirable characteristics on population uniformity, grain size, yield, adaptability, disease-resistance, etc. It was approved by the Approval Committee of Fujian Province in June,2014. This article details the breeding procedures, yield performance, and characteristics of Juliangyou 636.

Key words: hybrid rice, Juliangyou 636, high yield, resistance
