摘　　要：为筛选磷高效的小麦品种,采用双向平均作图法和GGE双标图法对21份供试小麦品种的株高、穗长和穗粒数等农艺性状以及产量指标进行综合评价。结果表明,新冬52号和石冬03112小麦为磷高效型品种,新冬49号为磷低效型品种。新冬20号、新冬48号和新冬26号3个小麦品种在不同的磷处理下对磷元素的吸收和利用能力存在差异。该试验结果可为快速规模化筛选磷高效小麦品种提供借鉴,并可为进一步研究磷高效小麦品种的基因调控机制提供材料。To screen wheat varieties with high phosphorus utilization, the agronomic traits including plant height, spike length, grain number per spike and yield indexes of 21 tested wheat varieties were evaluated by bidirectional average plotting and GGE biplot.The results showed that Xindong 52 and Shidong 03112 were varieties with high-efficiency phosphorus utilization, while Xindong 49 was variety with high-efficiency one.Three wheat varieties including Xindong 20,Xindong 48 and Xindong 26 had different capacities of phosphorus uptake and utilization under different phosphorus treatments.The results provided reference for rapid and large-scale screening of wheat varieties with high-efficiency phosphorus utilization, and provided material for further research on regulation mechanism of the phosphorus-related genes in these wheat varieties.
