The study looked at different types of wheat to see how they vary in traits related to grain yield. They found that there is a lot of genetic diversity among the wheat genotypes, especially in traits like grain yield, grains per spike, and 1000 grain weight. Traits like number of grains per spike and days to maturity showed high heritability, meaning they are strongly influenced by genetics. The researchers also found that grain yield is strongly correlated with test weight, number of grains per spike, and other traits. They discovered that traits like thousand grains weight and grains per spike have a big impact on grain yield, which could help improve wheat production in the future.
