摘要
采用层次分析法和效用函数法相结合的多目标决策技术,对农作物多目标育种中亲本选择方法进行了初步探讨.以玉米为例,建立了多目标育种综合选择函数,对1990年华北春玉米区试品种的16个自交系进行了例证分析.结果表明,由综合选择函数值排序前6位自交系参于组配的新品种,区试产量均高于对照农大60,这充分说明了育种选择函数的有效性.该方法原理简单,计算容易,能够把育种学家的知识、经验与系统工程学的定量分析法有机结合,是选择指数、典型相关等多元统计方法所不及的新的作物育种选择方法,对提高作物育种的相对效果,具有重要的理论和实践意义.
The article approached parents selecting method for multi-target crop breeding by adopting AHP(Analytica1 Hierarchy Process) and effectiveness function. Taking maize as example, we established Synthetical Selecting Function in Multi-target Crop Breeding, and analysed 16 inbred strains from varieties experimented with in North China spring maize region in 1990. The results showed that new varietties combined by the inbred strains whose synthetical selecting function values ranked among the first 6 places had higher outputs than variety Nong Da 60 (ck), which explained the effectiveness of selecting function in crop breeding. This method has merits of simple principle, easy calculation, and combination of breeder's knowledges and experiences with quantitative analysis of system engineering, and has an advantage over plural statistical methods such as selecting index and typical interrelation. Application of the method to crop breeding can improve breeding effect and is of important theoretical and practical significance.
