The F2 data from a 4 parent half diallel cross was used for combining ability analysis. Significant genetic variability existed for days to heading, days to maturity, plant height, number of spikes per plant, number of grains per spike, grain yield per plant and 1000 grain weight. The major portion of the total genetic variability for these traits was due to additive type of gene action. Small, but significant SCA estimates for most of the traits with the exception of days to heading and maturity suggests that some of the total genetic variability was due to non-additive type of gene action. The cross Faisalabad-85 x Rawal-87 had the best specific combining ability for grain yield per plant, while the best specific combining ability for number of spikes per plant, number of grains per spike and 1000 grain weight was found in case of the cross Faisalabad-83 x Rawal-87. Faisalabad-83 proved to be the best general combiner for grain yield per plant, number of grains per spike and 1000 grain weight. This cultivar offers the best possibility of exploitation in breeding programs to develop high yielding varieties. |
