Abstract

This study was conducted to determine the inheritance and expression of transgene in descendants ($T_1\;to\;T_2$ generation) of SOD2-transgenic petunia by PCR and RT-PCR analysis. The trangene was segregated as Mendelian inheritance pattern (3:1 or 1:0) in most of $T_1\;and\;T_2$ generation lines. Transgenic homozygous lines were obtained in T2 generation. It was identified that the transgene expressed stably in examined all plants of 6 $T_2$ lines. The representative morphological traits (plant height, flower diameter, and flower color) of $T_2$ plants were compared with those of non-transgenic plants.
