N2  - The 19° LAGOS consisted of 300 advanced lines from almost 20 wheat-breeding programs of the Southern cone region. Twenty-seven of the 46 cooperators returned the results for analysis and publication. Like the previous year, this eason was also marked by severe drought in most part of the region caused by the phenomenon of La Niña. As a result, the general crop and disease development was affected severely .The information regarding agronomic characters and disease infections evaluated by the cooperators was averaged and is presented in Table 2. Superior lines identified for resistance to an individual disease as well as showing superior performance to an additional group of other related diseases or representing wide adaptation are presented in Tables 3-11. This information is complemented by disease infection ratings at hot spots (Table 12) ;seedling reaction to various leaf rust virulences in Brazil and Uruguay (Table 13) , assessment ofindustrial quality parameters {Table 14) and entries selected at each location {Table 15). The drought conditions throughout the region did not allow adequate level of critical evaluation of the diseases even at key locations. However, several changes in the leaf rust virulences resulted in higher infection of this disease asinpreviousyear.ln addition, stripe rust remained high and severe not only in Ghileand Ecuador but also in normally dry location in the southern part of Argentina. The higher intensity of powdery mildew and spot blotch on the germplasm even in a dry year such as this causes serious concern forfuture germplasm development. The tan spot infection, which has been on an increase during these past years, was only moderate. Several advanced lines were selected by the cooperators for utilization in their breeding programs. On the basis ofwide adaptation and moderate to lo~v level of disease susceptibility to the three rusts, powdery mildew and leaf blights, the following entries: 112, 162, 186,206,245, 257, 258, 275 and 293 (presented in the table above) were selected
