Wheat (Triticum aestivum L.) is the most precious staple food and is highly regarded in the world as king of cereals. The present experiment was conducted to determine the combining ability analysis of 30 wheat hybrids and six parents viz., Iqbal-2000, Aas-11, SH-95, 9469, 9481 and 9486 for morphological traits in bread wheat. Data recorded for the traits including flag leaf area, number of spikelet per spike, number of grains per spike, 100-grain weight and grain yield per plant. All the studied traits were highly significant to specific combining ability (SCA)except flag leaf area. The genotype Iqbal-2000 was the best parent out of six parents involved due to its good GCA. So, this parent could be used in hybridization program for obtaining desirable genotypes. The crosses like Iqbal-2000×9469 and 9469×9481 good (SCA) showed their superiority and a cross SH-95×Aas-11 expressed reciprocal superiority for studied traits and could be further used for future breeding program and selecting desirable plants in the subsequent generations which may be useful in the development of varieties.
