Nine bread wheat (Triticum aestivum L.) genotypes were crossed in a line × tester mating design.
The 20 F1's and their parents were evaluated in a randomized complete block design with three replications at the Field Crop Institute-Agricultural Experimental Station of Setif (Algeria) during the 2011/2012 cropping season.
The results indicated that sufficient genetic variability was observed for all characters studied.
A899 × Rmada, A899 × Wifak, and A1135 × Wifak hybrids had greater grain yield mean than the parents.
A901 line and the tester Wifak were good combiners for the number of grains per spike.
MD is a good combiner for 1000-kernel weight and number of fertile tillers.
HD1220 is a good general combiner to reduce plant height; Rmada is a good general combiner to shorten the duration of the vegetative growth period.
A901 × Wifak is a best specific combiner to reduce plant height, to increase 1000-kernel weight and number of grains per spike.
AA × MD is a best specific combiner to reduce duration of the vegetative period, plant height and to increase the number of kernels per spike.
A899 × Wifak showed the highest heterosis for grain yield, accompanied with positive heterosis for the number of fertile tillers and spike length, and negative heterosis for 1000-kernel weight and the number of days to heading.
σgca2/σsca2, (σD2/σA2)1/2 low ratios and low to intermediate estimates of h2ns supported the involvement of both additive and nonadditive gene effects.
The preponderance of non-additive type of gene actions clearly indicated that selection of superior plants should be postponed to later generation.
