520 ## - SUMMARY, ETC.
Summary, etc. Head selections (2619) from 325 Triticum dicoccon Schrank accessions in the CIMMYT wheat collection were evaluated for their reaction to Septoria tritici in Toluca (Mexican highlands), during The S. tritici inoculum used was originally selected under controlled conditions by inoculating 10 durum cultivars with different isolates. The more virulent isolates were then used to inoculate susceptible emmer wheats, and re-isolate from them. These isolates were increased in a yeast sucrose liquid medium. Field inoculations were done weekly for three weeks, starting at the tillering stage with a 10 spore concentration using an ultra low volume sprayer. Thirty four percent of the selections were highly susceptible to either stripe rust (Puccinia striiformis) or leaf rust (Puccinia recondita) and were eliminated. Eleven percent of the selections were moderately to highly susceptible to S. tritici, 24 percent were extremely resistant to S. tritici but moderately to very resistant to both rusts. 31 percent were highly resistant to S. tritici and seemingly immune to both rusts. These emmer wheat accessions can be considered valuable for both bread and durum wheat improvement, and may well represent untapped sources of resistance.|Durante 1992, se evaluo en Toluca (Valles Altos de Mexico) la resistencia a Septoria tritici de 2619 selecciones de espiga de Triticum dicoccon Schrank. obtenidas de 325 entradas de la coleccion de trigos de CIMMYT. E1 inoculo de S. tritici usado fue seleccionado originalmente bajo condiciones controladas al inocular 10 cultivares de trigo duro con aislamientos de S. tritici. Los aislamientos mas virulentos fueron usados para inocular trigos emmer susceptibles y reaislarlos desde alli. Para las inoculaciones de campo, el inoculo se incremento en medio liquido de sucrosa levadura y se aplico tres veces tres semanas consecutivas, usando una aspersora de ultra bajo volumen a una concentracion de 10**(9) esporas por ml. Treinta y cuatro por ciento de las selecciones fueron eliminadas por ser altamente susceptibles, ya sea a roya estriada (Puccinia striiformis) o roya de la hoja (Puccinia recondita). Once por ciento de las selecciones fueron moderadamente a altamente susceptibles a S. tritici, 24 porciento fueron extremadamente resistentes a S. tritici, pero moderadamente a muy resistentes a ambas royas. Treinta y un por ciento fueron altamente resistentes a S. tritici y aparentemente inmunes a ambas royas. Estas entradas de trigos emmer pueden ser consideradas de valor para el mejoramiento tanto de trigos harineros como trigos duros, y pueden representar una fuente no utilizada de resistencia.
