ABSTRACT
Gene action for yield its contributing characters and biochemical characters in rice (Oryza sativa L.,) was studied in two selected crosses, involving three parents, including their F1’s, F2’s, and their back cross populations. The significant scaling test (one or more scales in A, B and C) indicate the presence of digenic epistasis in all the characters studied except in grain yield per plant which showed simple additive and dominance effect. Complex genetic behavior was observed in most of the characters. Since the segregation generations did not follow a simple Mendalian inheritance, high selection pressure is expected in later generations due to probable successful exploitation of additive and dominance component.
Key words: Generation mean analysis, Gene action, epistasis.
