Nine super sweet corn inbred lines with abroad germplasm T1, T2, T3, M1, M2, M3, R1, R2, R3 were selected as tested lines, and original inbred lines B, C, D, 6, D2 as testing ones in this examination. 45 crosses were made by means of incomplete diallel method, and the genetic parameters of the groups and the combing ability of 10 traits, growth period, plant height, ear height, ear length, ear diameter, core diameter, baldhead length, rows per ear, kernels per row, single ear weight were tested and analyzed by means of NCⅡ design.
