Abstract

24 hybrids generated by crossing four male sterile lines with six testers in line x tester fashion were studied along with their parents and checks (BIO-799 and PA 6129) for correlation and path analysis. The results emphasized the need for selection, based on plant type with greater plant height, number of productive tillers per plant, head rice recovery, milling percentage, spikelet fertility, panicle length and kernel length. Since, these traits were found to be the important direct contributors for grain yield.
