In order to study, compare and achieve new durum wheat cultivars more high yielding comparing to widely grown varieties, comprising resistance to diseases, lodging, shuttering and suitable quality for producing of semolina and determination of valuable plant genetic resources received from international centers to be used in crossing blocks and active contribution, this research project including the following three nurseries were implemented in 2003-2004 cycle. 1-IDYN(International Durum Yield Nursery) 2-EDUYT(Elite Durum Unreplicated Yield Trial ) 3-IDSN(International Durum Screening Nursery) In all replicated trials&rsquograin yield of each entry was weighted separately. combined variance analysis were implemented on the collected data based on statistical rules. High yielding lines / varieties, significant at 1% and 5% were selected for advance trials of next year. Plot size in replicated and observation nurseries were 3.6 m² and 1.2 m² respectively. Measurement of lines / varieties in observation nurseries with no replication as they were carried out in some locations, were in observation nurseries measurement and calculation of results were based on Rank method and each location was assumed as one replication. and superior genotypes participated in PRWYT in 2004-2005 cycle.
