只有准确地掌握新品种的主要优缺点,才能决定新品种的取舍。我们在评价新品种过程中,主要掌握以下原则: 1.推广依据:新品种推广,必须具备多年多点的品系(种)鉴定。品种比较和区域试验的结果,还要有一定的试种、示范面积,有了这几方面的材料,才有可能使新品种的优缺点充分暴露出来。在历年的各项试验中,表现高产、优质、抗逆性强、产量稳定的品种,在主要性状上比对照品种优越,其它性状与对照品种差不多,又能增产10%以上,或有其它优点等,一般说来,就可以大胆利
Only accurately grasp the main advantages and disadvantages of new varieties, in order to decide the choice of new varieties. We evaluate the new varieties in the process, mainly to grasp the following principles: 1. Promotion based on: promotion of new varieties, must have many years of strains (species) identification. Variety comparison and regional test results, but also have a certain species of trial, demonstration area, with these aspects of the material, it is possible to make the advantages and disadvantages of new varieties fully exposed. In the past years of experiments, the varieties with high yield, high quality, strong resistance and stable yield were superior to the control varieties in the main characters, other characters were similar to the control varieties, but also increased the yield by more than 10% or had other advantages In general, you can be bold and beneficial
