title: Cytogenetic structure of common wheat cultivars from or introduced into Spain.
abstract: Chromosome arrangements of twenty-eight cultivars of common wheat, Triticum aestivum L., from or introduced into Spain are compared with that of 'Chinese Spring' taken as a pattern. All the cultivars analyzed differ from 'Chinese Spring' by one or two reciprocal translocations. When 12 out of 28 cultivars were compared it was concluded that a minimum number of thirteen interchanges are present, involving at least ten different chromosomes of the complement. The interest of a reappraisal of the rôle of interchanges in the evolution of Gramineae is pointed out.
