Comment:
Derived from Ae. speltoides.
Further chromosome engineering on DAS15 showed that the alien segment carried two resistance genes. The gene on 2BL was considered to be Sr47 based on low infection type. The second gene located in 2BS produced a low infection type similar to Sr39 and was located in a similar position to that gene {10872}.

Tests of natural and induced mutants of P. graminis f. sp. tritici indicated that Sr45 has identical specificity to Sr21 {934}. One race distinguishing Sr45 and Sr21 is reported in {11134}.

Sr12 is more widespread and probably more effective in conferring resistance than is usually acknowledged {939}. Although the association of field resistance and Sr12 was not definitive allelism or close linkage is clearly involved {11104}.

Comment:
In rye Sr50 may be allelic with Sr31; however in wheat they can be regarded as separate loci Sr50 is located in a small interstitial segment not detected by GISH. Line T6-1 lacks the Sec-1 allele from rye {10745}.

Comment:
Recessive allele. Adult plant response.
Sr2 is associated with pseudo-black chaff{742,1102} and seedling chlorosis (see {149}) and occurs very frequently in commercial wheats, especially in germplasm produced and distributed by CIMMYT. Sr2 has probably remained effective since the 1920s. Lines combining Sr2 and Fhb1 are reported in {11170}; Sr2 is located about 2 cM distal to Fhb1.
