SUMMARYThe alcohol dehydrogenase (ADH), glutamic oxaloacetic transaminase (GOT), aminopeptidase (AMP), endopeptidase (EP), and esterase (EST) zymogram phenotypes of Chinese Spring wheat, Betzes barley, Chinese Spring-Betzes heptaploids, and a number of presumptive Betzes chromosome additions to Chinese Spring were determined. It was found that four disomic chromosome addition lines could be distinguished from one another and from the other three possible lines on the basis of the zymogram phenotypes of these isozymes.The structural gene Adh-H1 was located in Betzes chromosome 4, the genes Got-H2 and Amp-H1 in chromosome 6, and the gene Ep-H1 in chromosome 1. These gene locations provide evidence of homoeology between Betzes chromosomes 4, 6, and 1 and the Chinese Spring chromosomes of homoeologous groups 4, 6, and 7, respectively.

Isozyme markers were used to develop Triticum aestivum cv. Chinese Spring–Elytrigia elongata (= Agropyron elongatum, 2n = 14, genome E) disomic 3E and 5E addition lines. Subsequently, all possible lines containing 3E and 5E substituted for wheat homoeologues and several 3E and 5E ditelosomic addition and substitution lines were developed. Plants containing chromosome 3E substituted for wheat chromosomes of homoeologous group 3 are similar to 'Chinese Spring' in vigor and fertility while plants containing 3EL substituted for chromosomes of group 3 are less fertile than 'Chinese Spring'. This indicates that both arms of 3E are involved in sporophytic compensation. Plants containing chromosome 5E substituted for wheat chromosomes of homoeologous group 5 are as vigorous but less fertile than 'Chinese Spring'. 5EL (5A) and 5EL (5B) plants are lower in fertility than 5E (5A) and 5E (5B) plants, indicating that both arms of 5E are involved in sporophytic compensation. 5E (5D) and 5EL (5D) plants are similar in fertility. Male gametophytes in which 3E or 5E replaces a wheat homoeologue function at a lower rate than normal gametes.Key words: wheat, Triticum, Elytrigia elongata, alien chromosome addition lines.

SUMMARYThe possibility of using Hordeum bulbosum Crosses to facilitate production of disomic wheat–barley addition lines from monosomic additions was investigated. Aneuhaploids with 22 chromosomes were obtained in the expected gametic frequencies after crossing monosomic, disomio and monotelo-disomic addition lines, involving four different barley chromosomes, as the female parent with tetraploid H. bulbosum. Thus the added barley chromosomes were not eliminated when preferential elimination of the bulbosum chromosomes took place in the hybrid embryos. Disomic addition lines were obtained after treating the aneuhaploids with colchicine. This method could have wider application in the production of other wheat–alien chromosome disomic addition lines, especially where the transmission frequency of the alien chromosome through the pollen is very low, but its use will depend on the wheat parent being crossarle with H. bulbosum and the alien chromosome being retained during the elimination of bulbosum chromosomes.
