The stay-green trait is one of the factors that can aid the breeder in obtaining higher yielding plants due to a delay in leaf senescence, favouring grain filling. The objective of this study was to evaluate the performance of different wheat lines with and without the stay-green trait and investigate if longer green period; foster an increment of grain yield. The field experiment was conducted in randomized complete block design with three replications in two crop years. Genetically superior lines facilitate the benefits of the stay-green trait for grain yield. The stay-green trait promotes yield stability under different environments.
