Nine Mexican Triticum aestivum cultivars, derived from CIMMYT germplasm, and the US spring cultivar Wheaton were susceptible to the Mexican Puccinia striiformis pathotype 14E14 at the seedling growth stage but displayed different levels of adult plant resistance to the same pathotype when tested in the field. Some 118 random F2, F3 and F5 lines from crosses of these 10 resistant wheats and the susceptible cultivar Jupateco 73S were evaluated in the field. The moderate resistance of Penjamo 62, Lerma Rojo 64, Nacozari 76, Tesia 79 and Wheaton was under monogenic genetic control and was attributed to the stripe rust resistance gene Yr18. The moderate resistances of Cleopatra 74, Zaragoza 75 and Apache 81 were also monogenic, but gene Yr18 was absent. Pavon 76 carried 2 partially effective additive genes while the resistance of Tonichi 81 was based on additive interaction involving Yr18 and 2 additional partially effective genes. Tonichi 81 does not carry any seedling resistance gene but the resistance is highly effective worldwide. This resistance, designated as the Yr18 complex, is durable. The partial resistance of Pavon 76 has also remained durable in Mexico and other countries
