Genetic improvement of saffron (Crocus sativus L.): urgent problems

Y.M. Aghayev
Owing to heterogeneity of populations of saffron it was found that populations of saffron are a mix of 1) high degree multiflowered (ultra-extraordinary and extraordinary), 2) multiflowered (superior), 3) moderately-flowered (ordinary), 4) less flowered (inferior), 5) with 1-2 flowers or completely without a flower (declining) clones. The clones also differ viz-a-viz; number and size of corms. Creation of new cultivars will be carried out by further tests of ultra-extraordinary, extraordinary and superior clones and their vegetative propagation. Selection of clones needs to be done on the basis of two most important attributes: exclusively large amount of flowers and maximum number of large size (≥6 g) of corms. New cultivars being created on the basis of specified clones will possess mostly large corms, thereby making it easy to mechanize cultivation of plants (corm planting and digging). Every new cultivar will be created on the base of highly multiflowered clone, without mixing different clones. That is why each created new cultivar will be genetically homogeneous, of single clone origin. Homogeneity of cultivars will guarantee building of uniform leveled plantations of saffron with the added advantage of care after plantation and at mechanization of works.
