品系育种中细毛(半细毛)羊选择指数的研制和应用探讨

Discussion on the Development and Application of Selection Index in Fine-wool Sheep(Semifine-wool Sheep) in the Strain Breeding

品系育种是迄今畜禽纯种选育与杂交利用系统中最为安全高效的途径,综合选择指数则是多性状选择改良的理想方法。该研究试将综合选择指数与绵羊品系育种相结合,提供了一种制作"绵羊品系选择指数"的方法示例,以便高效可控并有预见性地推进绵羊品系育种进程。

So far,strain breeding has been the safest and the most effective way in the pedigree breeding and crossbreeding utilization system of livestock and poultry.The comprehensive selection index method is an ideal way of multiple traits selection and improvement.Combining the comprehensive selection index method with the strain breeding of sheep,a case of processing the method of sheep strain selection index was provided,so as to control effectively and advance the sheep strain breeding process predictably.
