A study on field peas looked at different traits like plant height, yield, and flowering time. Researchers grew 23 pea genotypes in a controlled experiment and found a lot of variability in the plants. Some traits, like plant height and seed yield, showed high variability, while others, like days to maturity, had less. They also found that traits like plant height and seed yield were highly heritable, meaning they are passed down from parent to offspring. The study showed that certain traits, like plant height and number of pods, had high potential for genetic improvement, while others, like pod length, had less room for change.
