2nd International Triticeae Symposium
Richard R-C. Wang
An open pollinated natural population and an inbred line of Dasypyrum villosum were cytologically examined. Nuclear DNA content, chromosomal distribution of the C-banded heterochromatin and the chromosomal site of action of restriction endonucleases were investigated. The results demonstrate that in D. villosum two classes of heterochromatin exist with different chromosomal location and reacting properties. One fraction of heterochromatin appears to be more affected by individual variation than the other. Preliminary examination of the chromosomal characteristics of D. breviaristatum indicate that the evolution of this latter species involved a more complicated process than the simple duplication of its chromosome number.
