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...

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...

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
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...

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...

Article
The cytogenetic structure of Vicia sativa aggregate
The cytogenetic structure of Vicia sativa aneuploid series was assessed by examination of the chromosome pairing in hybrids between types having 2n = 10, 2n = 12 and 2n = 14. Two different karyotypes were disting...

Domestication of the protein-rich tetraploid wild oats Avena magna and A. Murphyi
The first stage in the domestication of the protein-rich tetraploid oats Avena magna and A. murphyi has been achieved by introducing seed non-shattering from the cultivated hexaploid oats A. sativa. A great varia...

Genetic relationships among the annual species of Cicer L.
Genetic relationships between 7 annual species of the genus Cicer, including the cultivated chickpea, have been studied. These species were assigned to 3 crossability groups. In each group interspecific hybrids c...
