Barley diseases, including leaf rust, powdery mildew, net blotch, covered smut, BYDV, and loose smut are considered the most problematic. Surveys for these diseases have been carried out annually to study the virulence of disease isolates and to monitor the ongoing disease </B></div> <div> <B>Situation in Egypt. From the many samples received from neighboring countries, tests for race identification and genes conferring resistance have been made. From the efforts of the national project for loose smut disease of wheat, 14 physiologic races of stem rust have been identified, as seven leaf rust races. As a result, genes conditioning resistance for both leaf and stem rust have been identified. Genes that confer resistance in some Egyptian commercial varieties have also been identified. </B></div> <div> <B>Among other significant accomplishments in this area is the identification of loose smut isolates, which have been a problem since 1980. Sources of resistance have been identified and chemical control strategies have been developed.</B></div> <div> <B>Four physiological races of </B><I><B>Ustilago tritici </B></I><B>have been, identified for the first time in Egypt. Testing and selecting resistant genetic sources to loose smut from exotic and national germplasm are carried out in cooperation with the Wheat Breeding Program of the Field Crops Research Institute. </B></div> <div> <B>Another achievement of note is the sub-regional training course on cereal rust methodology, carried out in Egypt by the Cereal Disease Research Section. The course was organized and arranged by the International Center for Agricultural Research in the Dry Areas (ICARDA) and participants from Sudan Ethiopia joined Egyptians for the weeklong course</B></div> <div> <A HREF="id85_m.htm" TITLE="8 Cereal Disease:"><U><B><IMG SRC="1c74d320.gif" border=0 width="77" height="50" ALIGN="BOTTOM" HSPACE="0" VSPACE="0"></B></U></A></div> <DIV ALIGN="LEFT"></DIV> <div> <A HREF="index.htm" TARGET="_top" TITLE="_"><U><B><IMG SRC="1ae1e1e0.gif" border=0 width="30" height="30" ALIGN="BOTTOM" HSPACE="0" VSPACE="0"></B></U></A></div> <div> <B> </B><FONT SIZE="3" COLOR="#FF0033" FACE="Arial Black" ><B>Back</B></FONT><B> </B><FONT SIZE="3" COLOR="#FF0000" FACE="Arial Black" ><B>To</B></FONT><B> Home</B></div> </td> </tr></table></body>
