Abstract:The relativity characters of the nitrogen absorption and utilization were analysed under two levels of N supply (0 and 180 kg/hm2) by using forty five rice germplasms, which were divided into four types based on grain yield under two N rates, such as efficient-efficient(EE), inefficient-efficient(IE), inefficient-inefficient(II) and efficient-inefficient(EI). Focus on the research of variance analysis and correlation among characters related to grain yield, the N accumulation(NA) and nitrogen-use efficiency(NUE) between different types. The results showed that the range of variance of grain yield per plant,straw yield per plant, the NA and physiological N use efficiency(PNUE) were 4.50-29.65 g, 6.35-18.70 g, 4.80-21.28 g/m2and 19.88-62.05 g/g , respectively. Grain yield was significantly positively associated with effect panicles per plant(EP), spikelets per panicle(SP), seed setting rate (SSR), the BA, the N accumulation in grain(NAG), the NA and PNUE and significantly negatively associated with the N concentration in grain(NCG) and N concentration in straw(NCS) whether in low-nitrogen or high-nitrogen conditions. There were significantly different between grain yield(GY) with BA, NA and PNUE for four types of rice. EE and IE were the most influence by nitrogen fertilizer, EI was the least. The research showed that Qing-ma-zao, Lu-Cai-Zao, Guang-lu-ai 4, Zao89-01 and Zao-xian152 had been selected for tolerance-low nitrogen and high NUE type,among them, Qing-ma-zao and Lu-Cai-Zao is the typical high NUE type that showed higher, stable yield whether in low-nitrogen or high-nitrogen conditions; Guang-lu-ai 4 is the typical tolerance-low type that showed higher yield in low-nitrogen and suitable planted in poor soil, however, Zao89-01 and Zao-xian152 are suitable planted in fertilize soil that showed higher yield in high-nitrogen conditions.
