小麦与抗旱性有关的根系遗传改良研究进展

Review on Genetic Improvement in Root Related to Drought-resistance in Wheat

在全球许多地区,干旱胁迫已经成为限制小麦生产的主要因素。小麦根系性状的遗传改良(包括根系构型、根系数量、根系质量和根系解剖结构等)有利于同步提高作物的抗旱性和产量。本文对国内外与小麦抗旱性有关的根系遗传改良研究进行了综述,以期为小麦节水抗旱高产栽培和抗旱品种的选育提供参考。

Drought stress has been the main factor of limiting wheat yield. The genetic improvement of Root characteristics (root architecture, root quantity, root quality and root anatomic structure etc.)could contribute to improving crop drought-resistance and yield of wheat synchronously. This paper reviewed the (advance) of genetic improvement in root of wheat,and put forward the future research prospects.
