A study was conducted to evaluate 19 wheat genotypes for their performance in terms of grain yield and other characteristics. The researchers found significant genetic variability among the genotypes, with some showing higher grain yield potential. They also observed that environmental factors influenced the expression of certain traits. Traits like number of grains per spike and test weight showed high heritability, suggesting they are mainly controlled by genetic factors. The study also found positive correlations between grain yield and traits like biological yield, grains per spike, and test weight, indicating that improving these traits could lead to higher grain yield in wheat plants.
