Outline
In recent years, due to a series of issues such as global warming, delayed harvest of previous crops, and extreme weather conditions, wheat planting has been postponed and the growth period has been shortened, seriously affecting the high and stable yield of wheat and national food security. Late sowing has become the main limiting factor for wheat yield and quality improvement in the middle and lower reaches of the Yangtze River and even the Huang-Huai wheat region in China. This article summarizes the effect of late sowing on the growth and development of wheat, as well as the breeding of late sowing tolerant wheat. It is believed that in the future, research on late sowing tolerant wheat should mainly be carried out from the three aspects: physiological and genetic mechanisms, genetic improvement, and supporting cultivation techniques for late sowing wheat, in order to solve the problem of wheat late sowing and yield reduction.
