一个优良作物品种应具备高产、优质和稳定性强。对产量和品质的测定较为容易,而稳定性是个统计学概念,必须通过区域试验,在不同区域条件下测定作物品种的基因型与环境互作,以得到有关信息,利用这些信息可以对每个品种的丰产性、稳定性和适应性做出准确评价。同时还能对参试环境
A good crop varieties should have high yield, high quality and stability. The determination of yield and quality is relatively easy, and stability is a statistical concept. It is necessary to determine the genotypes of the crop breeds by interacting with the environment in different regional conditions through regional trials to obtain relevant information that can be used for each Variety of high yield, stability and adaptability to make an accurate assessment. At the same time can also test the environment
