Morphological characteristics of garlic (Allium sativum L.) genetic resources collection – Information

Maintenance of garlic (Allium sativum L.) genetic resources has had a long tradition in the Czech Republic. The collection was founded in 1951 and its current holder is the Crop Research Institute, Department of Vegetables and Special Crops in Olomouc. The collection consists of 613 genotypes. The oldest genotype was acquired in 1954. The collection has been evaluated according to the Descriptor list for Allium spp. (IPGRI 2001). 17 characters of the Descriptor list were supplemented with 5 additional characters. The photos of all garlic genotypes were taken. The genotypes were divided into the three main morphological groups according to the ability to produce the scape: the first group with the scape (bolting) – 300 genotypes, the second part without the scape (non-bolting garlic) 205 genotypes and the third part presents semi-bolting garlic – 108 genotypes. The last morphological type has bulbils in the different parts of the pseudostem.
