Hundred maintainer lines of hybrid rice were studied for correlation and path analysis at Indian Institute of Rice Research, Hyderabad. Grain yield per plant had significant positive correlation with productivity per day (0.95). Other traits, namely days to fifty percent flowering, number of productive tillers per plant, panicle length, panicle weight, number of grains per panicle has positive non-significant correlation with yield. Path analysis revealed that productivity/ day (0.96) was the major contributor for grain yield followed by, panicle weight (0.11), number of productive tillers per plant (0.10), days to fifty percent flowering (0.08), panicle length (0.03) and number of grains per panicle (0.01). It can be concluded from the study that, the above characters can be used as the selection criteria in any rice yield improvement breeding programmes.
