Genetic Diversity of several Inbreed Sweet Corn Lines for the Main Characters of the Ear
AbstractGenetic diversity of the inbreed lines used in hybrid formula is a major component of the final success of sweet corn commercial hybrids. The purposes of the presented paper were to identify and prognosticate the performance of Sugary 1 sweet corn inbreed lines, on the basses of their variability expressed at the phenotypic and genotypic levels. In this respect 18 inbreed su lines, developed at Turda (Romania) Agricultural Research and Development Station (ARDS) were studied concerning the phenotypic and genotypic diversity of ear weight, ear length, no. of rows/ear and depth of kernels. The results obtained have shown that T152su, T339su, TA28su, TD10su, TA26su, TC209su lines have registered high values for the phenotypic expression if the studied characters. T339su, TA28su transmit positive additive genetic effects for the studied characters. The most obvious differences at the non additive genetic level were found in T339Rsu with T244su, T193Asu with T233su, TC209su, TA27su with T244su si TC209su and T152su with TC209su.
