The study looked at how different traits in wheat plants are related to grain yield. By analyzing 238 wheat progenies, the researchers found that traits like plant height, number of tillers, and number of grains per spike were strongly linked to higher grain yield. This suggests that focusing on these traits in breeding programs could help create wheat varieties with higher yields. The researchers also found that traits like biological yield and harvest index had a direct impact on grain yield, indicating their importance in maximizing wheat production.
