农作物品种区域试验的作用是全面评价新育成(引进)品种的生育特点、农艺性长、丰产性、抗逆性和稳定性,为品种的审定和推广的适宜范围提供科学依据。区域试验的特点是通过多年、多点的品比试验,并通过恰当的统计分析,才能客观地反应出每个参试品种的真实面目。如果区试质量不高,则会影响试验结论,轻者使结论产生偏差,重者则会误判某个品种。实践证明,注意 The role of regional trials of crop varieties is to comprehensively evaluate the characteristics of fertility, long agronomy, high yield, stress resistance and stability of new breeding (introduced) varieties and provide a scientific basis for the validation and promotion of varieties. Regional testing is characterized by multi-year, multi-point trial, and through appropriate statistical analysis, objectively reflect the true face of each test variety. If the quality of the regional test is not high, it will affect the test conclusion, the light of the deviation of the conclusions, the heavier will misjudge a variety. Practice shows that attention
