Description An investigation was carried out in rice (Oryza sativa L.) to study the components of yield sink capacity; Among 17component characters analysed by correlation study, spikelets, grains, high density grains/panicle, secondary branches/panicle, spikelets, grains and high density grains on secondary branches were found to be important contributing charactersfor grain, yield/panicle. The varieties which registered high values for these traits also recorded higher grain Yield/panicle. 'Inter-correlation among these important contributing characters indicated strong correlation among themeselves suggestingsimultaneous improvement of these characters through a simple selection. The study suggests that while handling a largegermplasm or segregating populations by the breeders, secondary branches/panicle may be used as a criteria for selectionfor higher grain yield in rice, as recording of this character is simple and easy compared with other contributing characters.
