The study looked at different types of aromatic and pigmented rice to see how they vary in important traits like yield and grain weight. They found that some traits, like 1000 grain weight and number of tillers per plant, showed a lot of variation among the rice types. Traits like 1000 grain weight and biological yield per plant were highly heritable, meaning they are passed down from parent to offspring. The number of filled spikelets per panicle also showed high heritability and genetic advance, which means it can be improved through selective breeding. Overall, the study helps us understand how these rice varieties differ in important characteristics and how they can be improved for better yields.
