Could early gene flow have created similar allozyme-gene frequencies in cultivated and wild barley?
The possible role of early gene flow between wild and cultivated barley in their similar esterase gene frequencies was tested in a simulation study. The hypothetical population consisted of 99.9% wild forms po...

Giemsa C-banding in Avena insularis Ladizinsky
The Sicilian wild tetraploid oat Avena insularis is a close relative of A. magna and A. murphyi and is more plausible than either of these two species as the immediate tetraploid ancestor of A. sterilis and the o...

Cytogenetic relationships between Avena insularis (2n=28) and both A. strigosa (2n=14) and A. murphyi (2n=28)
The newly discovered tetraploid oat Avena insularis was crossed with the diploid A. strigosa and the tetraploid A. murphyi. Considerably reduced chromosome association at meiosis and a low average number of ch...

A new species of Avena from Sicily, possibly the tetraploid progenitor of hexaploid oats
A new species of oat, Avena insularis, is described. It was collected in southern Sicily where four populations were found on uncultivated clay soil. Morphologically, it is similar to the hexaploid wild oat A....

Cryptic speciation in Lens culinaris
Three crossability groups have been identified in the wild progenitor of lentil, Lens culinaris ssp. orientalis. The common one which is predominant in this taxon and in the cultigen, the unique one, which at pre...

Article
Genetic analysis and linkage study of seed weight in lentil
The genetics of seed weight was studied in crosses between the cultivated lentil L. culinaris and the wild species L. orientalis and L. ervoides. Seed weight was found to be under polygenic control with additive ...

Genetic affinity between two chemotypes of clary sage (Salvia sclarea L.)
A new and unique chemotype of clary sage, Salvia sclarea L., was identified recently in wild populations of this species in the northern part of Israel. This chemotype was crossed to a cultivated form of clary sa...

Article
Tertiary trisomics in lentil
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 ...

Thebaine content and yield in induced tetraploid and triploid plants of Papaver bracteatum Lindl.
The effect of colchicine induced autotetraploidy on the thebaine content and yield of the capsules of Papaver bracteatum was studied. A significant increase in the thebaine content of the capsules was found in te...

The genetics of hard seed coat in the genus Lens
Seeds of the cultivated lentil are capable of germinating shortly after maturation. The seed dormancy of wild lentil species is due to a hard seed coat. In crosses between the cultivated species L. culinaris and ...
