Abstract
This study was carried out at the Scientific Research Center in Raqqah, arranged in a randomized complete block design (RCBD), during the growing seasons 2012-2013-2014, to study of genetic behaviour of 29 genotypes (21 maize hybrids, 7 inbred lines and basel-1was control) under 4 levels of salinity (0, 4, 8, and 12) m moss, to determine mid-parents heterosis (%), and heritability for 100 kernel weight (g) and grain yield (ton/ha). Significant differences were noticed between hybrids in different levels of salinity and the effect of interaction between two factors, salinity and genotype. All hybrids were influenced at 8, and 12 m moss level of salinity, but with different degrees. Seven hybrids had exceeded the control at the level of 8 m moss, and P4XP7 recorded the best value in grain yield (7.633 t/ha) and heterosis value (59.5**) at the same level of salinity. Also, nine hybrids had exceeded the control, and P2XP3 showed the best value in grain yield (5.642 t/ha) and heterosis value (45.8**) at 12 m moss level of salinity.
Key words: Maize, Genetic Behaviour, Heterosis, Salinity.
