近年来,新选育和新引进的品种愈来愈多,新品种与新品种之间、推广品种与推广品种之间、新品种与推广品种之间,在产量上、品质上和稳定性方面都有明显差异,各品种的经济性状、抗逆力和适应性,也很不相同。为了正确评定良种,使其在适应地区得到充分利用,必需切实搞好品种区域试验。如果未经区域试验,就把各种新育成或新引进的品种盲目应用到生产上去,容易招致品种“多、乱、杂”,使一些表现不良的品种,不能及时淘汰,而真正
In recent years, new varieties of breeding and new introduction more and more, between new varieties and new varieties, between the promotion of varieties and promotion of varieties, between new varieties and promotion of varieties, in terms of yield, quality and stability There are obvious differences, the economic traits of each species, resilience and adaptability, is also very different. In order to correctly assess the elite so that they can be fully utilized in the area of adaptation, it is necessary to do a good job of testing the varieties in different regions. Without the regional test, all kinds of newly bred or newly introduced varieties are blindly applied to production, which can easily lead to varieties of “chaos, miscellaneous, and miscellaneous”, so that some varieties with poor performance can not be eliminated in time but the real
