中文摘要：

为了筛选养分高效且稳定性好的小麦基因型材料，对连续多年（1991—2001）的不施肥（CK）、单施氮肥（N）、氮磷配施（NP）、氮钾配施（NK）、磷钾配施（PK）、氮磷钾配施（NPK）6种施肥处理下的不同基因型小麦产量及其构成进行分析。结果表明，小麦产量构成在年际间的变化幅度及变异系数（CV）均受施肥方式影响，缺素施肥处理（N、NP、NK、PK）中豫麦13亲缘系、临汾7203、郑州941以及豫麦47群体穗数、穗粒数在年际间变化较大；NPK处理中临汾7203、郑州941群体穗数及豫麦47穗粒数在年际间变化依然较大；各基因型小麦的千粒重在6种施肥处理中年际间变化均较大。6种施肥处理中临汾7203、郑州941以及豫麦47群体穗数CV较小，而豫麦13亲缘系、郑麦9023~在NPK处理中CV较小；缺素施肥处理中各基因型小麦穗粒数CV均较大；千粒重CV仅有临汾7203的NP处理、豫麦47的NK处理和郑麦9023的CK、NP、NPK处理略高，其他基因型小麦较小。除亲缘系豫麦13和郑州8998外，其他基因型小麦年际间产量变化趋势在6种施肥处理中相近，且均在施氮肥处理中存在较大差异。

英文摘要：

In this paper,the yield and its components of different wheat genotypes with six fertilization methods between years,including CK（no fertilizer）, N （single nitrogen fertilizer）, NP（ nitrogen and phosphorus fertilizer）, NK （nitrogen and potassium fertilizer）, PK（phosphorus and potassium fertilizer）, NPK（nitrogen, phosphorus and potassium fertilizer）, were analyzed. The results showed that differences and coefficient of variation（CV） of yield components between years were all influenced by the fertilization methods. Both spike number and grain number per spike of Yumai 13 relatives,Linfen 7203, Zhengzhou 941 and Yumai 47 with the treatment of N,NP,NK, PK were greatly changed between years; both spike number of Linfen 7203 and Zhengzhou 941 and grain number per spike of Yumai 7 with the treatment of NPK were still greatly changed between years; 1000-grain weight of all genotypes with six fertilization methods were greatly changed between years too. In addition, CV of spike number of Linfen 7203, Zhengzhou 941 and Yumai 47 with six fertilization methods were lower, the same phenomena in Yumai 13 relatives and Zhengmai 9023 with the treatment of NPK were also found;CV of grain number per spike of all genotypes with the treatment of N,NP,NK,PK were higher;CV of 1000-grain weight of Lin-fen 7203 with the treatment of NP,Yumai 47 with the treatment of NK and Zhengmai 9023 with the treatment of CK, NP, NPK were slight high, the others had the lower CV. Additionally, variation trends of wheat yield with six different fertilization methods were quite similarly except Yumai 13 relatives and Zhengzhou 8998,and there were large differences among the treatments with nitrogen fertilizer.
