Effects of waterlogging on grain yield and associated traits of historic wheat cultivars in the middle and lower reaches of the Yangtze River, China

Frequent waterlogging events have severely constrained wheat production in the middle and lower reaches of the Yangtze River, China (YR). Understanding the effects of waterlogging on agronomic traits and grain yield in historic wheat cultivars can help establish strategies for stable- and high-yield breeding programs. We conducted a two-year field experiment using 10 winter wheat cultivars that were released and widely planted in YR from 1967 to...
