It is worthwhile mentioning that old cultivars grown till 1980, had stalks longer than 1.5 m while mutant cultivars, grown presently, are around 85-90 cm. Mutant cultivars currently cover almost the whole durum wheat area in the country. A big part of the durum wheat is exported. High quality mutant characteristics are preferred for the production of pasta. The use of mutant cultivars has significantly increased the productivity of durum wheat. Nowadays these durum wheat cultivars attain a grain yield almost equal to commom wheat.
