Abstract
Aneuploid stocks in durum wheat are few, and alien additions are particularly rare. The present contribution describes the results of a program aimed at the addition of alien chromosomes to tetraploid wheat. Aegilops caudata, Ae. longissima and Dasypyrum villosum were used as chromosome donors. The crossing program involved the production of amphidiploids with the wheat cytoplasm and the recurrent crossing with durum wheat pollen. IS monosomic addition (2n= 29) plants were obtained and partly selfed and/or backcrossed to wheat. Two disomic addition (2n = 30) plants, possessing two different Ae. caudata chromosomes, were obtained; unfortunately they were very weak and highly sterile, thus preventing their further propagation. The difficulties experienced during the development of the crossing program are discussed in detail.
