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
