Abstract: 48 rice genotypes were used for researching nitrogen absorption and utilization efficiency, and the relationship between nitrogen utilization efficiency (NUE) and main agronomical characteristics. The results were showed that there was significant difference of NUE between different rice genotypes, and the high NUE genotypes would be selected from the entry materials. Chang-lun-zhan is the typical high NUE genotype that showed higher, stable yield whether in low-nitrogen or high-nitrogen conditions. Two rice genotypes e.g. Guang-hui 128 and Mo-li-zhan-xuan, and three genotypes e.g. 97-xiang, 2466 and Yin-hua-zhan had been selected for high NUE type under low-nitrogen condition and high-nitrogen condition, respectively. The high NUE type under low-nitrogen condition is suitable planted in poor soil, and the NUE type under high-nitrogen condition are suitable planted in fertilize soil. The results were also showed there was significant correlation at 0.05 level between NUE and SPAD value of top 2nd and 3rd leaf in heading and milk stages, harvest index, grain yield and panicle number, respectively. So, these traits could be used for indices of NUE evaluation. So, it is issue how to coordinate the relationship between nitrogen absorption efficiency (NAE) and NUE so that not only increasing grain yield nor improving NUE because there was significant negative correlation at 0.01 level between NAE and NUE.
