Summary: Spot blotch of wheat, caused by Bipolaris sorokiniana (syn. Helminthosporium sativa), is an important wheat disease in China. The main varieties currently grown in China are susceptible to the disease, and sources of resistance are limited. A research program was undertaken in 1988-92 to improve resistance by developing a practical procedure for somaclonal selection for spot blotch resistance. Resistance enhanced mutants were obtained from four spring wheats. After field testing the regenerated plantlets for four successive generations, resistance was found to be stable. Resistance evaluation in the field suggested that in vitro selection of embryonic calli using H. sativa toxins was effective. The mutants obtained expressed higher levels of stable, heritable resistance.
