Abstract

Nine genotype of wheat, Triticum aestivum L. (Intisar, Sham6, Tamoz2, IPA99, 11-1, 25-1, 3-1, AL-Iraq and AL-Rasheed) and half diallel crosses gained with according with the 2nd method suggested by Griffing (1956), were used in this study. Genotypes (9 parent + 36 single cross) were planted at AL-Hawija – Kirkuk Province, in winter season 2013-2014, using the randomized complete block design with three replications to study genetic behavior for characters,(plant height (cm), spike length (cm), number of spike/ plant, flag leaf area cm2, days to ful bloom(day), biological yield, number of grains per spike, grain yield (g), 1000 grain weight(g), harvest index, yield efficiency and protein percentage), through the estimation of general and specific combining The results can be summarized as follows All parents and F1 showed significant difference for all characters at 1% level. The ratio general combining ability to specific combining ability component were less than one for all characters The Parent Al-Iraq showed general combining ability for most studied characters and hybrids (Intisar × 11-1), (Tamoz2 × IPA99), (Tamoz2 × 25-1), (Tamoz2 × AL-Rasheed), (IPA99 × 11-1), (25-1× AL-Iraq).
