Breeding of New Wheat Varieties Huanan T2003 and T531 with Resistance to Scab Gibberella zeae (Schw) petch

A recurrent selection breeding procedure was designed by means of laigu genic(Tal) male sterile gene and employed to develop new wheat varieties with resistance to scab. Fu-Fan No. 17 with the gene Tal and other eight wheat varieties(lines) with resistance to scab were used to construct the base population of recurrent selection, New scab-resistant varieties Huanan T2003 and T531 were developed from the plants that were selected after one cycle of selection by pure line breeding method. The experience of developing new wheat variety with resistance to scab using recurrent selection method was briefly summarized.
