Professor: Dr. Jerome D. Franckowiak.
Twelve genes (Rphl to Rphl2) have been reported to control the resistance to Puccinia hordei Otth in barley (Hordeum vulgare L.). This study was conducted to (1) develop 'Bowman' backcross-derived lines differing in the Rph genes, (2) identify new Rph genes, and (3) map the new Rph genes in barley chromosomes using morphological markers.
