提高品种区域试验质量,是做好品种审定工作的重要条件之一。新疆自治区在常用的完全随机区组设计中,每个重复里增设一个相同的对照小区,利用双重对照区提供的信息,辨别试验误差的主要来源,对各个试点的试验质量作出评价,从而推进品种区域试验的不断改进。材料和方法 1986年新疆冬个麦品种区域试验,参试品种为461、318、75(144)、76(13)、7639—3—9、新冬2号6个品种。其中,新冬2号为对照。每个重复设两个小区,称CK_1和CK_2。在试验设计时,按7个品种看待,随机决定它们在区组中的位置。试点有伊犁、洛甫、皮山、泽普、轮台、喀
It is one of the important conditions to do a good job in the examination and approval of varieties to improve the quality of regional trials. Xinjiang Autonomous Region In the commonly used completely randomized block design, an identical control plot is added to each repetition. The information provided by the double control plot is used to identify the main sources of experimental errors and to evaluate the test quality of each pilot so as to promote the varieties Regional testing continues to improve. MATERIALS AND METHODS The regional trials of Xinjiang winter wheat varieties in 1986 were conducted. The tested varieties were 461,318,75 (144), 76 (13), 7639-3-9 and Xinxin 2. Among them, Xin Dong 2 as a control. Each repeat set two cells, called CK_1 and CK_2. In the experimental design, according to seven varieties of view, randomly determine their position in the block.
