Five subtelocentric primary trisomics of Vicia faba L . were isolated from crosses between asynaptic mutants and normal plants or translocation tester stocks . The extra chromosome of each trisomic was identified cytologically by critical multivalent association at metaphase I of meiosis .

β¦ Synopsis
The inheritance of purple seedling colour was studied, in relation to the genetic control of flower colour. It was found that purple seedling colour is likely to be controlled by a single gene and that the trait is dominant over green seedling colour. White flowering prohibited the expression of the purple seedling colour, and is therefore thought to be epistatic.
This character can be used to estimate rate of outcrossing in breeding programmes, as well as contribute to our knowledge of the biosynthesis of plant pigments and secondary metabolites such as tannins.

Because of the partially insect cross-pollinated nature of faba bean (Viciafaba L.), ICARDA maintains two types of faba bean germplasm collections. The ILB (International Legume Faba Bean) collection consists of the original germplasm accessions as received, usually heterogeneous and heterozygous. F
To increase the level and stability of yield in faba beans (Vicia faba L.), heterosis must be exploited. Hybrids are not available because of the instability of male sterility. Synthetic varieties can and should be bred. Thus, we studied the reproductive behavior of this partially allogamous, insect
From faba bean (viciu faba 15.). two new saponins were isolated by Sephadex LH-20 gel filtration, ODS column chromatography and semi-preparative HPLC. Their molecular weights determined by FAB-MS were 978 and 962, respectively. Results of TLC and FTIR ana-lyses showed that these compounds are simila
Tissue slices from developing potato tubers (Solanum tuberosum L.) and developing cotyledons of faba bean (Viciafaba L.) were incubated with specifically labelled [13C]glucose and [13C]ribose. Enriched [13C]glucose released from starch granules was analysed by nuclear magnetic resonance (NMR). Spect
The distribution of the pyrimidinone glucopyranosides vicine and convicine was investigated in resting seed and axenic developing seedlings up to 17 days of age in Viciafaba cv Troy, a low seed pyrimidinone glucopyranoside mutant (MTG5) derived from Troy, and a related species V narbonensis. The low
