Abstract As the male parents,56 single plants out of seven inbred lines were crossed to pepper(Capsicum annuum L.)CMS line 8A,and the resulting F1 hybrids were used for the identification of restoration lines.The results showed as following:the fertile plants generated plenty of pollen grains which were dyed by TTC and took on red,while,the sterile plants generated no or few pollen grains which were dyed by TTC and took on no color.Besides,there were 4 out of 7 inbred lines,which had certain restoring ability,and among them there were one plant in inbred lines R2 and two plants in inbred lines R8 that had 100.0 % restoration ratio.Thirdly,the major agronomical characteristics of the 3 restoring crossings were better than their parents,and their heterosis was very obvious.
