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...

On the Origin of Almond
Almond, Amygdalus communis L., is an ancient crop of south west Asia. Selection of the sweet type marks the beginning of almond domestication. Wild almonds are bitter and eating even a relatively small number ...

Identification of the lentil's wild genetic stock
The origin of lentil from the taxon Lens culinaris subsp. orientalis has been proved by morphological evidence and breeding experiments. This wild form exhibits variation in many characters and is distributed ...

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....

Characterization of the missing diploid progenitors of the common oat
The genomic formula ACD of the hexaploid oat,Avena saliva, AC for the tetraploid speciesA. magna andA. murphyi, and the hypothesis that the A genome was contributed byA. strigosa group and C genome byA. ventricos...

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...

Genetic characterization of Lens ervoides from Ethiopia
A single population of the Mediterranean species Lens ervoides was located in Ethiopia and seeds were collected. Based on chromosomal arrangement and isozyme profile the Ethiopian L. ervoides is similar to popula...

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...

Pulse domestication before cultivation
Comparative studies of the pulses of the Middle East and of their wild progenitors indicate that the pattern of pulse domestication is completely different from that of cereals in the same region. Wild legumes...

Session I. Genetic Resources and Their Use in the Breeding of Oats Chairman’s Comments and Summing Up
Advance in plant breeding depends upon the availability of genetic variability. Land races and primitive varieties were used in breeding programmes in the past, but more recently may have been neglected when b...

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 ...

Founder effect in crop-plant evolution
Seed-crop plants apparently originated from a limited number of mutants in which seed dispersal was changed from that found in nondomesticated populations. Seed nonshattering in cultivated plants may be contro...

Rescue of interspecific lens hybrids by means of embryo culture
A two-stage in vitro technique was established for the development of interspecific hybrid embryos in the genus Lens. The culture of 14-day-old fertilized ovules on MS medium supplemented with zeatin, followed by...
