Morphological traits of DT23 and its wheat parents were evaluated in the field in Wenjiang district, Sichuan Province, China, with three replications in the 2020–2021 growing season. At the physiological maturity stage, 20 randomly selected plants of each line were harvested to evaluate their morphological traits, comprising plant height, tiller number, spike length, number of spikelets per spike, number of kernels per spike, and 1,000-grain weight. The IBM SPSS Statistics 24.0 software package was used for statistical analysis of the data.
