ABSTRACT

In 6x6 diallel cross, heterosis was studied in 15 F1. The variances due to heterosis were significant for all the characters. Overall heterosis partitioned into components and showed that average, variety and specific heterosis were significant for plant height, harvest index, days to 90% maturity and grain yield per plant. Spikes per plant estimated significant variety and specific heterosis and 100-grain weight estimated significant average and variety heterosis. Spike length and grains per spike showed only significant specific heterosis. Mid parent heterosis for grain yield per plant was observed maximum (110.34%) in the cross P3xP6.
