一个优良品种不仅要在较好的环境条件下能获得高产,而且在较差的环境条件下也能获得较好的产量,这就是品种的稳产能力即稳定性。从广义的角度可把品种的稳产性和适应性看成是一致的。品种的生产能力是品种遗传基因型在环境条件作用下的表现,在遗传学上称为基因型与环境的互作,这种 A fine variety not only to obtain high yield in better environmental conditions, but also in poor environmental conditions can get better yield, which is the stability of the species that is stable. From a broad perspective, the stability and adaptability of varieties can be seen as the same. Variety production capacity is the performance of the variety genotypes under the influence of environmental conditions, which is genetically referred to as genotype-environment interaction. This
