The inheritance of resistance to wheat leaf rust incited by Puccinia recondita Rob. ex Desm. f. sp. tritici , was investigated in ‘Leeds’ durum wheat ( Triticum durum Desf.) All F 1 plants of reciprocal crosses between Leeds and the rust‐susceptible line ‘D6618’ were susceptible to culture 70‐1 (race 1) P. recondita . The segregation ratio of approximately 15 susceptible plants: 1 resistant plant in the F 2 generation suggests that resistance is conditioned by two recessive genes, and this was confirmed when 281 F 3 families satisfactorily fit a 2‐factor 7:4:4:1 ratio.
