一、研究背景我国盐碱耕地面积约有1亿亩,盐害已引起了作物大量减产,培育耐盐新品种迫在眉睫。然而作物耐盐性是由多个数量性状位点(QTL)控制的复杂性状,遗传机理十分复杂。因此克隆耐盐QTL对于阐明作物耐盐机理和育种应用均具有重要意义。本项研究定位了一批水稻耐盐QTL,成功
I. Research Background The area of saline-alkali arable land in China is about 100 million mu. Salt salvage has caused a lot of crop production cuts and it is imminent to cultivate salt-tolerant new varieties. However, salt tolerance of crops is a complex trait controlled by multiple QTLs, and the genetic mechanism is very complicated. Therefore, cloning salt tolerance QTL for clarifying the salt tolerance mechanism of crops and breeding applications are of great significance. This study mapped a group of QTLs for salt tolerance in rice
