The study looked at different types of brinjal plants to see how they vary genetically. They grew nine types of plants and found that some traits like plant height, number of fruits per plant, and fruit yield per plant showed a lot of variation. This means that these traits are likely influenced by the genes of the plants. The researchers also found that traits like plant height, number of branches per plant, and fruit yield per plant can be inherited and passed down to future generations. This suggests that selecting plants based on these traits could lead to better overall performance.
