玉米单倍体诱导率及加倍率影响因素研究进展

Research Progress of the Effective Factors on the Induced Rates and the Doubling Rates of Haploid in Maze

单倍体育种是建立在遗传标记技术上的一种新兴的玉米育种技术,具有缩短育种周期,克服远缘杂交的不亲和性及合成育种新材料等优点。为更好地进行玉米单倍体育种技术研究及应用,简要介绍了玉米单倍体育种技术的研究概况及特点,重点阐述了玉米单倍体诱导率及加倍率在不同生态环境、不同播期、不同遗传背景等因素下的变化并就其在玉米育种领域的应用潜力进行了探讨。

Haploid breeding is an emerging maize breeding technology based on the genetic marker technique.It has such advantages as shortening the breeding cycle,overcoming the incompatibility of distant hybridization and synthetic breeding of new materials,etc.So as to provide references to the research and application of maize haploid breeding technology,brief introduces the research situation and characteristics of maize haploid breeding technology,focuses on the change in maize haploid induction rate and doubling rate in different ecological environments,at different sowing time,under different genetic background and other factors,and also discusses its potential application in the maize breeding field.
