Abstract

Genotypic correlation and path co-efficient analyses were carried out in F3 populations of two intervarietal crosses of rice for grain yield and its components. Tiller, number, panicle length and plant height showed positive correlation with grain yield. Hundred grain weight exhibited negative correlation with grain yield. Due stress must be laid on number of productive tillers per plant and panicle length during the selection for higher yield in rice.
