品种试验中最优参试品种个数和重复次数的确定

Determination of the Optimum Number of Tested Varieties and Replications When Testing Varieties

本文在下列两个准则下对品种试验中参试品种个数和每一参试品种的重复次数进行优化：（１）试验小区数固定为Ｎ的条件下使选择响应Ｒ最大化；（２）选择响应指定为Ｒ的条件下使试验小区数Ｎ最小化．

The optimum number of tested varieties and replications is determined to maximize genetic improvement for a fixed total plots or minimize total plots for a predetermined genetic improvement when testing varieties.
