| Abstract | ||
| The present study was carried out at the Experimental Farm of Sakha Agricultural Research Station,Sakha,Kafr EL-Sheikh Governorate and El-Sirw Agriculture Research Station, Dammietta Governorate, Egypt, during 2016 and 2017 growing seasons to study the inheritance of some growth traits, yield and its components under normal and saline soil conditions and to study the relationship between some growth characters and yield and its components by estimating correlation coefficient between studied characters.Results showed that location mean squares were found to be highly significant for all growth characters and yield and its attributes, indicating wide differences between the stress and non-stress conditions.Salinity condition has a negative effect on all studied traits for all genotypes compared with that of normal conditions.The interactions of genotypes,parents and crosses with locations (Sakha and El-Sirw) were detected to be highly significant for grain yield and its component except for harvest index, indicating that the genotypes behaved differently from non-stress to stress conditions.The parents Giza 178 and GZ9057 recorded the highest mean values of grain yield under normal and saline conditions as well as their combined data,while the parent Sakha106 gave the lowest mean value under the same conditions.Grain yield/plant was highly significant positively correlated with each of plant height, number of tillers/ plant, 1000-grain weight, panicle length, number of filled grains/panicle and harvest index.The results revealed that the studied genotypes were expected to similarly a broad spectrum of variability and confirmed the detected significant among these parents. Euclidean distance was ranged from 17.59 between (GZ6296 and Sakha 106) to 71.23, between (Giza 178 and Sakha 105) under stress conditions. | ||
