黄瓜耐盐胁迫遗传育种研究进展

Research Progress on Genetic Breeding of Cucumber Tolerance for Salt Stress

盐胁迫是影响黄瓜生长发育的主要逆境因子之一。开展黄瓜耐盐胁迫研究,培育耐盐品种,对于提高黄瓜耐盐性和盐碱地的利用率具有重要意义。本文主要从黄瓜种质资源耐盐性评价,盐胁迫对黄瓜生长发育及生理的影响,黄瓜耐盐性遗传分析及相关基因挖掘,以及提高黄瓜耐盐性的主要途径等四个方面进行综述,着重阐述了近年来黄瓜耐盐胁迫育种的研究进展。同时提出了目前黄瓜耐盐胁迫育种研究中存在的问题,并对今后的研究方向进行了展望。

Salt stress is one of the main abiotic stresses affecting cucumber growth and development.It is of important significance to carry out studies on cucumber tolerance for salt stress and cultivate salt tolerant varieties for improving cucumber salt tolerance and increasing use ratio of saline-alkali land.This paper reviewed the following 4 aspects:evaluation of salt tolerance in cucumber germplasm resources;effects of salt stress on cucumber growth,development and physiology;genetic analysis and genes mining related to cucumber salt tolerance and major measures for improving cucumber tolerance to salt stress,etc.Emphasis was laid on research progress made in cucumber breeding for tolerance to salt stress in recent years.At the same time,the paper put forward the problems existing in current research on cucumber breeding for tolerance to salt stress,and prospected the research directions in future.
