%X A line กม tester analysis involving five varieties SQ-26, SQ-77, GH-10, 8670, PARC-N2 (lines) and three varieties 8721, SARC-5 and DN-4 (testers) were crossed to study some hydroponics growing characters. In controlled conditions SQ-26 exhibited the highest positive GCA effects on Shoot length, Shoot fresh weight, Na+ and K+ concentrations, while SQ-77 showed maximum GCA effects on Root length, Root fresh weight and Shoot dry weight in females and in males and both DN-4 and SARC-5 showed the highest GCA effects. Under high saline concentration female SQ-77 showed the maximum positive effects on all characters but on shoot length and Na concentration while male SARC-5 exhibited the highest positive GCA effects on all characters. Under high saline level, the cross combination SQ-26 กม 8721 showed SCA effects for shoot length, whereas 8670 x 8721 showed the same effects for shoot fresh weight, root fresh weight and root dry weight. For Na+ and K+ concentrations, the cross combination GH-10 กม DN-4 showed then highest SCA effects, whereas for shoot dry weight and root length, the cross combinations GH-10 กม SARC-5 and PARC-N2 กม 8721 showed the highest SCA effects, respectively.
