Abstract
The pattern of inheritance of isozyme alleles was examined in the F 2 progeny of a sexual cross between two different physiologic races of the wheat stem rust pathogen, Puccinia graminis Pers. f. sp. tritici Eriks. &Henn. Segregation occurred at five isozyme loci (Got, Lap, Nadhd, Pgi-2 and Pgm-1). In all of these, the observed number of F 2 progeny of each of the three possible isozyme phenotypes did not differ significantly from a simple 1:2:1 ratio. Joint dihybrid segregation indicated that three of the loci formed a single linkage group: Lap–Nadhd–Pgi-2.Key words: linkage, segregation.
