在过去的十年中,植物育种的着重点和某些概念发生了重大的变化。例如:群体表现与个体表现的关系,保留残余的遗传变异性代替了高度的近亲繁殖,宁愿选择广泛适应性而不选择对本地区的高度适应性,群体生物化学的多面性,对病原菌的耐病性以维持病原与寄主之间的动态平衡代替了免疫性,以及表型的一致性与遗传的多样性相结合和以前追求的表现型与遗传性的一致性成为鲜明的对比等等。其他与产量有关的株型改良指标,例如矮秆对多量肥料与灌溉的反应,群体结构的控制,光的不敏感性,对恶劣环境的忍耐力等,也都得到了应用。
Over the past decade, there have been major changes in the focus and certain concepts of plant breeding. For example: the relationship between population performance and individual performance, to retain the residual genetic variation instead of a high degree of inbreeding, would rather choose a wide range of adaptability rather than choose a high degree of adaptability to the region, group biochemistry, versatility, pathogenicity In order to maintain the dynamic balance between pathogen and host instead of immunity, as well as the consistency of phenotype and genetic diversity combined with the previously sought-after phenotype and genetic consistency in sharp contrast and so on. Other yield-related plant form improvement indicators, such as the response of dwarf to large amounts of fertilizer and irrigation, population structure control, insensitivity to light, endurance to harsh environments, have also been applied.
