Hua-03 is a newly released high-protein, early indica variety with wide adaptability in Hubei Hunan, Kiangsi, and Kwangsi Provinces (23.0-32.0 degrees North, 107-120 degrees East). It was derived by anther culture from IR8/Er-Jiu-Qing F2 during 1978-88. The new variety usually ripens 3-5 d earlier than popular local variety Guang-Lu-Ai4. In regional large-scale plantation trials in Hubei and Kiansi 1986-88, average yield was 7 t/ha, nearly 10% higher than that of Guang-Lu-Ai4. Hua-03 has better nutritional quality and palatability and higher milling rate. An outstanding characteristic of Hua-03 is its high-protein content, especially of the eight essential amino acids. Brown amino acids score was 67% in preschool children and 89% in school children.
