冬小麦再高产 育种涉及到的目标 性状是众多的 数量性状， 要对这些 数量性状 同时进行 改良并重 新加以组装，进而育 成产量水平有较 大突破的新品 种，必须首先 突破原有 的传统育 种方法，在 杂交手段和杂种后代处理这两个关键 性技术环节上进行较大的改进。本文把轮回选择 的理论和穿梭育 种的方法 综合运用到冬小麦 再高产育种实践 中去，进一步强化了 轮选穿梭 思路在冬 小麦育种 实践中的 可操作性。
The target traits involved in the re-high yielding winter wheat breeding are numerous quantitative traits. If these quantitative traits are to be improved and reassembled at the same time, new breeds with large breakthroughs in yield level must be breached first through traditional breeding methods, In the hybrid means and hybrid offspring processing these two key technical aspects of major improvements. In this paper, the theory of reincarnation and the method of shuttle breeding are comprehensively applied to the practice of re-breeding high-yielding winter wheat, which further strengthens the maneuverability of the round-robin shuttle idea in winter wheat breeding practice.
