✦ Synopsis

Monogenic lines resistant to leaf rust of spring and winter wheats were grown in the world wheatproducing areas from 1970 through 1975. Lines containing the alleles Lr9 (Wi), Lr9 (Tc), and Lrl9 (Tc) were more resistant to the leaf rust pathogen than those containing Lrl (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 Lrl (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.

Using monosomic analysis genes governing resistance in one wheat variety, 'E5883', against stem rust races 15C and 122, were located on specific chromosomes. Against race 15C, a major dominant gene, Sr6, was located on chromosome 2D of 'E5883' with minor modifiers found on chromosomes 4A and 6D. Aga

The genetic constitution of two bread wheat accessions from the International Spring Wheat Rust Nurseries (E 5883 and E 6032) has been studied for reaction to four Indian races of stem rust. Analysis of E 5883 has revealed that for each of the races 15C, 21 and 40 a single dominant gene operates for

Crosses were made between the highly susceptible Little Club and the partially resistant cultivars Westphal 12A, Akabozu and BH 1146 to obtain F1, F2 and backcross generations . Latency period (LP) was determined in plants inoculated at the young flag leaf stage with a monospore culture of race `Fla
