| Abstract: | Summary Tertiary trisomics have been selected among derivatives of hybrids between the cultivated lentil and its wild progenitor Lens orientalis, and between the cultivated species and L. ervoides. Hybrids heterozygotes to a single translocation were more useful as a source of trisomic plants then those heterozygotes to a number of translocations. The trisomic plants were weeker compared to the euploid plants and many have not reached maturity. The meiosis, fertility and transmission rate of the extra chromosome were studied in a single trisomic line. |
