摘　　要：对重穗型小麦品系95－2生长动态分析结果表明，95－2较一般概念上的栽培品系株型粗壮、高大．在整个生育期保持较高的有效光合面积，形成较高的生物学产量，根系发达，形成大穗大粒，体现了源大、库大的特点，茎拜系统也具良好的输导性能。在下一步超高产、稳产品种培育中，植株叶型及其合理配置是一个着重要考虑和解决的问题。High weight spike wheat line 95-2 was dynamically analyzed during its growth. 95- 2,which is distinct from general cultivated varieties, has big and strong stalks. It kept high effective photo-synthesis area in its lifetime, produced high biomass, and formatted heavy spike and grain. Strong produc-tivity and storage capacity were a distinct feature of 95-2, and in the same time its stem kept high matter transportability. The problem of leaf type is the first of all to be considered and resolved in the future of the super yield breeding.
