本文考虑了具有预先规定的空间相关结构的早代品种试验设计，并介绍了一类新的部分重复设计，称为p-rep设计，其中标准品种的地块被附加的试验品系地块所取代。我们展示了如何使用改进的反应式禁忌搜索算法轻松生成高效的p-rep设计。在仿真研究中比较了p-rep和网格小区设计的期望遗传增益和实现遗传增益。
This article considers the design of early generation variety trials with a prespecified spatial correlation structure and introduces a new class of partially replicated designs called p-rep designs in which the plots of standard varieties are replaced by additional plots of test lines. We show how efficient p-rep designs can be readily generated using the modified Reactive TABU search algorithm. The expected and realized genetic gain of p-rep and grid plot designs is compared in a simulation study.
