  To estimate heterosis over mid-parent and better-parent of F1 hybrids in Brassica napus L. an experiment was conducted during 2004-05 and 2005-06 using 8x8 full diallel crosses. All the 56 F1 hybrids and their parents were planted in a randomized complete block design with three replications. Out of 56 hybrids, positive mid-parent and better-parent heterosis were found in 44 and 32 hybrids for number of pods/raceme, in 27 and 19 hybrids for number of pods/plant, in 27 and 15 hybrids for pod length, in 26 and 20 hybrids for number of seeds/pod, in 50 and 39 crosses for 1000-seed weightand in 21 and 07 crosses for yield/plant. However, significant positive mid-parent and better-parent heterotic effects were recorded in 44 and 32 hybrids for pods/raceme, in 26 and 19 hybrids for pods/plant, in 11 and 09 hybrids for pod length, in 21 and 20 hybrids for seeds/pod and in 07 and 04 crosses for 1000-seed weight. Better-parent heterosis reached to 66.67% for pods/raceme, 60.85% for pods/plant, 16.03% for pod length, 27.27% for seeds/pod, 54.62% for 1000-seed weight and 1.02% for grain yield. Among parents, NUR1, NUR4, NUR5, NUR7, NUR8 and NUR9 proved to be superior when used as parents in most of the hybrid combinations. Crosses NUR1xNUR7, NUR1x NUR9, NUR5x NUR4, NUR4xNUR9, NUR3xNUR9 and NUR8xNUR9 were best for yield associated traits and their further utilization in breeding programmes would be useful for developing high yielding genotypes.
