Rice (Oryza sativa L.) is the major staple foodÂ crop for more than half of the worldâ€™s population andÂ plays a pivotal role in food and nutritional security by
providing 43 percent of the calorie requirement. In theÂ coming decades, demand for rice is expected to keepÂ intensifying along with the growing population. India isÂ the second-most densely populated country and hence
the prime objective of plant breeders would alwaysÂ be an improvement in the productivity of the economicÂ product. In rice, grain yield is the ultimate criterion forÂ developing a high yielding variety. However, straightÂ selection for grain yield alone remains ineffective sinceÂ it is a complex trait and influenced by many componentÂ characters. The rapid improvement in grain yield isÂ possible only when selection is practiced for componentÂ traits also for which knowledge on inter relationship ofÂ plant characters with yield and among them isÂ essential. Therefore, in the current study correlation
analysis was carried out for understanding the natureÂ of association between grain yield and its componentÂ traits.
