Abstract

A field experiment was conducted during Rabi, 2009-10 and Kharif, 2010 involving 7 parents, 7 F1 hybrids and their corresponding F2 populations to study the inbreeding depression and residual heterosis for kernel characters i.e. kernel length, kernel breadth, L/ B ratio in aromatic rice. The cross combinations, PUSA1121 × BM71 and PUSA1121× MTU1010 for kernel length were identified as better crosses for further advancement to develop pure lines with high yield and quality.
