Thirteen characteristics were described on 89 clones of shallot (Allium cepa var. ascalonicum) as follows: foliage colour, foliage attitude, leaf diameter, degree of leaf waxiness, height growth, plant growth habit, shape of mature dry bulbs, population uniformity of bulb shape, bulb skin colour, average number of bulbs per cluster, retaining common tunica scales, ability to produce scape, and widened scape on the clones of shallot. The interrelations between plant vigour - foliage attitude, plant vigour - leaf diameter, height growth - foliage attitude, and leaf diameter - foliage attitude were statistically positively significant. The growing conditions and the temperature of storage influenced the bolting during the experimental period. The number and size of bulbs per cluster were influenced by the size of bulbs. The results are used for the evaluation of shallot genetic resources maintained in the Gene Bank of the Research Institute of Crop Production, Olomouc, Czech Republic.
