如何评价小麦种质资源亲本的可利用性,一直是育种家极为关注的事.近年来,笔者研究了近千份国内外多种类型小麦种质资源.本文表述了采用三种评价程序同步鉴定和研究的结果,试图查明亲本特定性状的遗传特点,从理论和实践上综合评定利用其亲本的可行性,为新品种选育提供依据和材料.一、综合评价方法(一)引种观察圃的初步鉴定对新引进的材料,查明来源、原产地、系谱及其性状特点或种子特点.在整个生育期间,详细记载农艺性状为主的生物学特性及在自然感病条件下,对主要病害和逆境的抗性表现,与本地区现有推广品种进行分析比较,初筛的材料,复鉴一年或同步进入鉴定 How to assess the availability of parents of wheat germplasm resources has always been a great concern to breeders.In recent years, the author studied nearly a thousand varieties of wheat germplasm resources at home and abroad.This paper describes the use of three evaluation procedures simultaneously identified And research results, trying to identify the genetic characteristics of the specific traits of parents, from the theory and practice of comprehensive assessment of the feasibility of using their parents, to provide the basis for breeding new varieties and materials. I. Comprehensive Evaluation Method (A) Of the initial identification of the newly introduced materials to identify the origin, origin, pedigree and traits or characteristics of the seed throughout the reproductive period, detailed biological characteristics of agronomic traits and natural conditions, the main Disease and adversity of resistance performance, with the promotion of existing varieties in the region for analysis and comparison, screening of materials, re-reference a year or simultaneously into the identification
