Haplotype variations in QTL for salt tolerance in Chinese wh

发布时间：2021-07-09 23:27

　　Most modern wheat cultivars were selected on the basis of yield-related indices measured under optimal fertilizer and irrigation inputs. With climate change, land degradation and salinity caused by sea water encroachment, wheat is increasingly subjected to environmental stress. Moreover, expanding urbanization increasingly encroaches upon prime agricultural land in countries like China, and alternative cropping areas must be found.Some of these areas have moderate constraining factors, such as s...
