Genotypic differences and valuation in nitrogen uptake and utilization efficiency in triticale
小黑麦氮素吸收利用的基因型差异研究

In this study, sixty-nine triticale varieties were employed to evaluate their total nitrogen accumulation (TNA), nitrogen harvest index (NHI), nitrogen transportation efficiency (NTE) and nitrogen utilization efficiency (NUE) at tillering, heading and maturity stages under a same N addition. The correlation analysis indicated that TNA and NUE were significantly correlated with the yield per plant (r=0.84, r=0.63). The results of cluster analysis indicated that Clxt75, P1428736, P1429227 and P1466703 had high yield per plant, TNA and NUE.
