TABLE. Karyotype parameters of 8 hyacinth cultivars.

Cultivars	Average AR	LC/SC	Chromosome number (AR>2)	ASK (%)	Sum of CI	LC- SC	Sum of 1/AR	m type chromosome number	sm and st type chromosome number	Karyotype type
According to the cytological indexes of H. orientalis, 8 cultivars were analyzed by Q-type cluster analysis with SPSS 21.0 software (Figure 4). At a euclidean distance of 20, the eight cultivars were clustered into three groups. There were 4 cultivars in Group I: ‘Purple Sensation’, ‘Blue Pearl’, ‘Odysseus’ and ‘Gypsy Queen’. ‘Yellow Stone’, ‘Red Pearl’ and ‘Pink Pearl’ comprised Group II. ‘Gypsy Princess’ alone was separated into Group III, of which Group II was relatively close to Group I in terms of genetic relatedness.
