The study looked at different types of lentil plants to see how they vary in seed yield and related traits. They found that some traits, like plant height and number of branches, can be improved by selecting the best plants early on. Other traits, like seed yield per plant, are more influenced by the environment. They also discovered that seed yield is strongly linked to harvest index and biological yield, while traits like seed weight and number of seeds per pod are connected to flowering time and plant height. Overall, the study shows that different traits in lentil plants are interconnected and can be improved through selective breeding.
