Abstract 

Panicle exsertion in the rice plant was strongly influenced by the toprnost three leaves before the milky stage of growth. The Reduction Division Stage was the most critical growth stage in this aspect. These leaves exert their influences in a complementary manner. Varietal differences in this character were due to differences in parental heritage. For Bahagia and Murni, the responses in panicle exsertion to defoliation treatments of the topmost three leaves were similar. With increasing levels of nitrogen application no clear trend in panicle exsertion was found.
