摘　　要：以杂交籼稻冈优22为材料,研究不同海拔高度种植对稻米外观品质的影响,结果表明,在相同齐穗期前提下,低海拔(300-400 m)和高海拔(700-800 m)种植的冈优22外观品质均劣于中海拔(500-600 m),外观品质与其他品质性状相关不密切,建议可在中海拔区域(最优种植区域)生产优质大米。Abstract： With indica hybrid rice Ganyou 22 as materials, the difference of rice appearance quality traits among different altitudes was studied. The main results were as follows： under the same full heading stage condition, the rice appearance quality traits of Ganyou 22 grown in middle altitude region （500 -600 m） were better than that in low （300 -400 m） and high （700 -800 m） alti- tude region, and there were no significant differences in correlations of rice appearance quality traits and other traits. High quality rice production arranged in middle altitude region was reasonable.
