New Diversity Arrays Technology (DArT) markers for tetraploid oat (Avena magna Murphy et Terrell) provide the first complete oat linkage map and markers linked to domestication genes from hexaploid A. sativa L.
Nutritional benefits of cultivated oat (Avena sativa L., 2n = 6x = 42, AACCDD) are well recognized; however, seed protein levels are modest and resources for genetic improvement are scarce. The wild tetraploid, A...

Dwarfing genes in the genus Lens Mill.
Dwarfing genes were detected following intra- and interspecific hybridization in Lens. Dwarf phenotypes are controlled by two complementary dominant genes, Df 1 and Df ...

Chloroplast DNA variation and evolution in the genus Lens Mill
Chloroplast DNA (cpDNA) restriction site diversity was assessed by 21 enzyme/probe combinations in 30 accessions of six Lens species, including the recently recognized L. lamottei and L. tomentosus. A total of 1...

Domestication via hybridization of the wild tetraploid oats Avena magna and A. murphyi
The wild tetraploid (2n=28) oat species Avena magna and A. murphyi have been domesticated by having been transferred from the common oat, A sativa (2n=42), the characteristics of non-shedding spikelets glabrous a...

Inheritance and linkage relationships of morphological and isozyme loci in chickpea (Cicer arietinum L.)
Inheritance and linkage relationships of several morphological and isozyme loci are described in chickpea (Cicer arietinum L.). Segregation data obtained from several F2 families confirmed the previously observed...

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 ...

Phylogenetic and genetic studies in Papaver section Oxytona: cytogenetics, isozyme analysis and chloroplast DNA variation
Chromosome behaviour at meiosis, isozyme studies and analysis of the chloroplast DNA restriction fragments were used to assess the phylogenetic relations among the three Papaver species of the section Oxytona. Th...

Genetic map** of an ancient translocation in the genus Lens
Segregation of 18 marker genes was monitored in selfed progeny of a Lens culinaris × L. ervoides hybrid; five linkage groups were mapped, one of which contained a reciprocal translocation break-point that differe...

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...

Article
Phylogenetic studies in Papaver section Oxytona: cytogenetics of the species and interspecific hybrids
Chromosome behaviour at meiosis was studied in the F1, F2, and backcross generations, in the three species of Papaver section Oxytona, and in artificially induced autopolyploids of P. bracteatum. Close homology w...

Article
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 ...

Article
Hybridization in the genus Lens by means of embryo culture
The cultivated lentil L. culinaris and the wild lentil L. ervoides are reproductively isolated from one another due to their hybrid embryo breakdowns. Using embryo culture, vegetatively normal hybrids were obtain...

Article
Genetics of allozyme variants and linkage groups in lentil
The genetics of 8 electrophoretically detectable enzymes in lentil was examined. The enzyme systems glutamic-oxaloacetic transaminase, malic enzyme, phosphoglucomutase, alcohol dehydrogenase, 6-phosphogluconat...

Restoration of meiotic regularity and fertility among derivatives of Lens culinaris x L. Nigricans hybrids
The wild lentil, L. nigricans is cross compatible with the cultivated species. Chromosome pairing in their F1 hybrids is highly irregular due to a difference of three translocations between the parental species. ...

Seed protein profiles of pigeon pea (Cajanus cajan) and some Atylosia species
The seed protein profile of pigeon pea (Cajanus cajan) appeared to be highly stable. The standard profile of this cultigen was found in 86 of the 90 accessions examined. Each of the Atylosia species, A. lineata, ...

Article
The origin of lentil and its wild genepool
Following hybridization experiments and cytogenetic analysis of interspecific hybrids three chromosome interchanges were found between the cultivated lentil L. culinaris and L. nigricans, and only one between the...

A case of genome partition in polyploid oats
At the second generation of the interspecific cross between the cultivated hexaploid (2n = 42) oat A. Sativa and the wild tetraploid (2n = 28) A. Murphyi, a plant having hexaploid and diploid (2n = 14) sectors wa...
