Abstract

A method was devised to obtain weighted values for the additive direct and maternal genetic effects of a single trait, estimated using a selection index to maximize the accuracy of selection. A method maximizing the square of the selection accuracy was used. This method should facilitate optimal genetic evaluation when the economic weights of direct and maternal genetic effects are unknown or difficult to establish.

直接和母系遗传效应的加权值，以最大限度地提高指数选择的准确性。

设计了一种获得单个性状直接遗传效应和母系遗传效应加权值的方法，利用选择指数对其进行估计，使选择的准确性最大化。采用了一种使选择精度平方最大化的方法。当直接遗传效应和母系遗传效应的经济权重未知或难以确定时，该方法应有助于最优遗传评价。

期刊介绍： Animal Science Journal (a continuation of Animal Science and Technology) is the official journal of the Japanese Society of Animal Science (JSAS) and publishes Original Research Articles (full papers and rapid communications) in English in all fields of animal and poultry science: genetics and breeding, genetic engineering, reproduction, embryo manipulation, nutrition, feeds and feeding, physiology, anatomy, environment and behavior, animal products (milk, meat, eggs and their by-products) and their processing, and livestock economics. Animal Science Journal will invite Review Articles in consultations with Editors. Submission to the Journal is open to those who are interested in animal science.
