The transfer of gene of resistance to tribenuron-methyl to sunflower breeding material of VNIIMK

Introduced from the USA the genetic stocks of SURES-1 and SURES-2 showed full resistance to sulfonylurea herbicide of Pulsar (a.i. tribenuron- methyl). Resistance to tribenuron-methyl in F1 and F2 in the crosses of these genetic stocks with breeding lines was controlled by one fully dominant gene. Nine donor lines with resistance to sulfonylurea herbicides were developed and works on the development of resistant analogs of six breeding lines of VNIIMK were finished.
