Abstract
Linkage studies can expedite the transfer of agronomically important genes in breeding programs A study was conducted to determine the linkage relationship between loci segregating for stem rust (Puccinia graminis Pers.:Pers. f. sp. tritici Eriks. & E. Henn.) resistance (Rpg1) and a chlorina mutant (f5), and to confirm the linkage among Rpg1, br1 (brachytic) and f(c) (chlorina seedling). 'Bowman' barley (Hordeum vulgare L.) was crossed to genetic stocks possessing br1,f(c), and f5, respectively. Estimates of linkage distances were 9.6 +/- 1.4% between Rpg1 and br1, 13.6 +/- 1.8% between Rpg1 and f(c), and 25.9 +/- 2.6% between Rpg1 and f5. The linkage between Rpg1 and f5 was established.
