作物品种区域试验,一般采用数年多点的联合试验,其目的是把各地经过品种比较试验选拔和推荐出来的最好的品种统一分送到各种不同的农业区域,以进一步鉴定新品种的丰产性、稳产性和适应性,并为扩大试验示范、推广应用提供科学依据。对多点试验所获数据的处理,以往主要是通过方差分析对参试品种多年多点的平均产量进行显著性测量来评价品种 Regional trials of crop varieties, the joint use of more than a few years the joint test, the purpose is to go through the various varieties of comparative trials selected and recommended the best varieties of uniform distribution to a variety of different agricultural areas in order to further identify new varieties High yield, stability and adaptability, and provide scientific basis for expanding experimental demonstration and popularization and application. To deal with the data obtained from the multi-point experiment, in the past, the variance was mainly used to make significant measurements on the average yield of the tested varieties for many years to evaluate the varieties
