    Notes: Summary The taxonomic relationships between 52 accessions of 12 Vicia species and three accessions of Lathyrus were examined using nuclear RFLP- and PCR-generated data. Two hundred and sixty informative restriction fragments or amplification products were analysed by single linkage analysis, average cluster analysis, and the Wagner parsimony method. Dendrograms constructed from each type of analysis showed similar overall topologies and could be divided into three parts corresponding respectively to the Lathyrus outgroup, the species grouped in the section Faba/narbonemis complex, and the species belonging to the sections Hypechusa and Peregrinae. With few exceptions, the majority of accessions belonging to one species grouped together before branching to other species. An analysis of mitochondrial DNA phenotypes was both consistent with and complemented the results from the nuclear data. Overall, the species relationships show a good correlation with the classification of Maxted et al. but suggest that V. faba is more closely aligned to species from the sections Hypechusa and Peregrinae than to those in the narbonensis complex. In addition, the position of two new species, V. kalakhensis and V. eristaloides, as members of the narbonensis complex was supported by the molecular data, which also allowed a preliminary classification for recently collected Vicia accessions.

    Notes: Summary The chloroplast DNA of 27 potato cultivars and 2 wild species has been examined by Southern blotting using probes representing the entire chloroplast genome of barley. 16% of the probe × enzyme combinations detected polymorphism between the potato cultivars. Cvs Maris Piper, Croft, Shelagh, Stormont Enterprise and Estima and the wild species could be distinguished from the other cultivars by their chloroplast DNA restriction patterns. These results are discussed in relation to cytoplasmic diversity and potato improvement.

    Notes: Summary Solubilities of bis-(2,2′-bipyridyl)- and bis-(1,10-phenanthroline)dicyanoiron(II) are reported for a range of primary aliphatic alcohols, from MeOH to 1-decanol. The established trends are compared with those for other solutes, and for the title compounds in H2O-alcohol solvent mixtures.
