反推亲本式玉米杂交组配及组合高效筛选思路
首发时间:2008-10-14
摘要:本文针对玉米育种的杂交组合筛选效率低的问题,提出了反推亲本式玉米杂交组配及组合高效筛选策略,对其实施的具体技术原理和步骤进行了详细说明,从杂交组合推断亲本过程的分子指纹技术非常关键。该方法和常规育种选择思路特点相反,是根据杂交组合的田间表现的效果来推断亲本的可能组成。对于目前该方法存在的问题和解决办法进行了综合分析和思考。

Retrospective Analysis of Hybrid Parents and Efficient Hybrid Cross Screen Protocol
Abstract:A Retrospective analysis of hybrid parental lines and hybrid cross screen protocol was constructed according to the relatively low cross screen efficiency till today through comprehensive analysis of the traditional selection method, which could greatly improve the cross selection efficient by about hundreds of times. Practical steps were also fully described. The protocol depends on the cross performance to deduce its possible cross derivation of male father lines based on several technique such as SSR fingerprint profile and careful control of breeding nursery. The substantial problems and relative solutions were also listed to help better understanding of the protocol.
Keywords: Retrospective analysis cross evaluation DNA fingerprint profile maize breeding single plant maize
