Morpho-physiological and yield components of rice are important character that affect the crop yield potential. Seeds as a sink of crops, its yield are very much determined by the panicle yield components, one of which is various type of tillers. The purpose of the research was to study the variability of panicle types andtheir relationshipwith grain yield of rice. Thirty rice varieties/lines were planted and observed in experimental pots. The study revealed that there are differencesin total number of panicle among varieties or lines. Average number of panicle ranges from 20–50 panicle. Among varieties, there were also differences in total number of panicles grown from primary, secondary, tertiary and quarterly tillers. The number of empty seeds of the panicles increases in the order of the sequences of tiller emergence, i.e., main panicle (11%), primary (12%), secondary (12%), tertiary (16%) and quartery (22%). High yielding rice could be obtained through the development of varieties or cultivation techniques that enable the crops produce more panicle in primary and secondary tillers compare to that in tertiary and quarterly tillers.
