杂交种的生产能力是基因型与环境条件作用下的表现,凡杂交种(基因型)因环境条件改变而引起生产能力的差别,在遗传学上称之为基因型与环境的互作。这种互作效应的大小反映了杂交种稳定性能的高低,互作效应大则杂交种的稳定性能低,反之,则表现为稳定性能高。为了确定优良杂交种的适应范围,往往需要经过多年多点试验。但为使
The ability of hybrids to produce is a function of genotype and environmental conditions. Where hybrids (genotypes) differ in their ability to produce due to changes in environmental conditions, they are genetically referred to as genotype-environment interactions. The size of this interaction reflects the level of stability of hybrids, the interaction effect is large, the stability of hybrids is low, on the contrary, the performance of the high stability. In order to determine the range of good hybrids often require more years of trial. But to make it
