| 摘要: |
| 利用灰色系统理论,对2001~2002年度杂种小麦品比试验结果进行了分析。结果表明,主要性状对杂种小麦产量贡献的关联度顺序为千粒重>穗数>穗粒数>株高。在各参试组合中,以西杂5号表现最好,其次为2611/8727,西杂1号。 |

| Abstract: |
| By means of gray system theory,the 2001-2002 result of yield contrast test of hybrid wheat was analyzed.The result showed that the order of relational grades of important characters to yield in hybrid wheat crosses was 1000-gram weight> No.of spikes (104/hm2) > No.of grains per spike>plant height.Among the crosses,Xiza 5 was the better one,2611/8727 and Xiza 1 were next. |
