| 摘 要： | 以盆栽 12个小麦品种为试材 ,研究表明 ,不同小麦品种的根干重、穗数、地上部干重、地上部干重 /根干重和产量之间存在着明显的基因型差异。除地上部干重 /根干重与产量无显著相关外 ,其余性状与产量呈显著或极显著相关 ,他们共同关系到产量水平。通径分析表明 ,地上部干重对产量的直接影响最大 (0 9713) ,根干重次之 (- 0 116 3) ,而根系主要通过地上部干物质来影响产量水平

| Abstract: | The 12 wheat cultivars under pot cultivated condition were used in this experiment.The results showed that there were significant genotype difference among root dry weight(RDW),spica number(SN),top dry matter weight(TDMW) and root top ratio(RTR).These characteristics were significantly or most significantly related to yield,except for RTR,and they attributed to yield level.The path analysis results indicated that the direct influence of TDMW on yield is the biggest(0 971 3),following by RDW(-0 116 3).In addition,the indirect effect of root on yield level was done by effect on TDMW |
