Abstract
The applied biotechnology including tissue culture, anther culture, in vitro screening of cell mutants resistant (or tolerant) to DON toxin, and transferring scab resistance genes from wild species to wheat was studied. Combined use of these biotechnological measures with traditional breeding method was practised in breeding wheat for scab resistance. In the passed 5 years, 14 highly resistant and 23 moderately (or upper moderately) resistant lines were developed. Among them were “895004” and “92P28”, which were examined and approved by the seed authority of Jiangsu Province and large scale trails are undergoing. “894037” and “894013”, have been used as resistant resources in breeding program now. Some high yield lines with moderate resistance to scab are being tested in the field.
