R, resistant; APR, adult plant resistance.
aResistant to all Indian pathotypes of stem rust.
bGenes were not postulated.
cLeaf tip necrosis gene Lr34.
dRust resistance genes present in these two varieties have not yet been identified (may have been detected in the source countries, but we do not have the information); presence of Sr2 (adult plant slow rusting stem rust resistance gene) in BARI Gom 27 is to be confirmed.
