Abstract
The pattern of inheritance of isozyme alleles was examined in the F2 progeny of a sexual cross between two different physiologic races of the wheat stem rust pathogen, Puccinia graminis Pers. f. sp. tritici Eriks. and Henn. Segregation occurred at five isozyme loci (Got. Lap. Nadhd, Pgi-2 and PgM-1). In all of these, the observed number of F2 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.This publication has 0 references indexed in Scilit:
