Abstract
Monogenic lines resistant to leaf rust of spring and winter wheats were grown in the world wheat-producing areas from 1970 through 1975. Lines containing the alleles Lr9 (Wi), Lr9 (Tc), and Lr19 (Tc) were more resistant to the leaf rust pathogen than those containing Lr1 (Tc), −1 (Wi), −1,3 (Wi), −2A (Tc), −2A (Wi), −2D (Tc), −3 (Tc), −3 (Wi), −10 (Tc), −16 (Tc), −17 (Tc), −18 (Tc), or −2D (Pld). Monogenic line Lr1 (Wi) possibly has more than one gene for resistance and resistance properties similar to cultivars with ‘field resistance’. A computer data base was created to produce the information used in this paper.
