任何一个品种,从育成到推广,必须通过品种区域试验,在区域试验过程中,设置对照品种,是为了给审定新品种确定一个评比的标准。每个参试品种,只有在与对照品种比较之后,才能衡量它是否有推广的价值。因而,对照品种在区域试验中,具有极其重要的意义。它的质量标准是否可靠,能否代表原来种性等问题,都直接影响到其它参试品种(系)推广或淘汰的命运。 Any one variety, from breeding to promotion, must pass the regional trials of varieties, in the regional testing process, the establishment of control varieties, is to determine the approval of a new breed of a standard. Each tested variety can be measured as to whether it has a promotional value if compared to a control variety.
