摘　　要：作物品种区域试验多年资料系参试品种在试验年份、地区上重复数不等的非平衡资料。本文根据最小二乘原理提出对这类资料进行分析的方法,以获得地区、品种、地区品种组合的最小二乘均数,检验其差异显著性,评价参试品种的生产能力,确定其适宜区域,为品种推广和合理布局提供依据。Crop variety regional trials in several years result in unbalanced data in which every variety was tested in different years and sites. Based on the least squares principle, an analyzing method of this kind of data was proposed to estimate the least squares means (LSM) of varieties, sites and their combinations, and to test significance of difference of LSMs. In this way, the productivities of the varieties could be evaluted and its suitable regions could be determined, to provide statistical basis for variety released area.
