Synopsis

Evaluated in the present paper according to the IPGRI descriptor were 37 onion genotypes (nine lines, nine populations and 19 cultivars). The following traits are described in the paper: leaf color, leaf length, leaf cross-section, leaf erectness, presence of leaf wax, bulb skin color and bulb flesh color. Trait variability was determined by PCA analysis, the results of which indicated great variability for bulb skin color, bulb flesh color, leaf length and leaf color. Using the hierarchical method, the onion genotypes were classified into four groups and 19 genotypes that do not belong in any of the groups but are related to them at various hiearchical levels.

Key words: onion, evaluation, PCA analysis, hierarchical clustering

Sinopsis

EVALUACIJA GENOTIPOVA CRNOG LUKA (ALLIUM CEPA L.)

U radu je prikazana evaluacija 37 genotipova crnog luka (devet linija, devet populacija i 19 sorata) po deskriptoru IPGRI. Prikazane su sledeće osobine: boja lista, dužina lista, presek lista, položaj lista, prisustvo voštane prevlake, boja suvih i boja sočnih listova lukovice. Varijabilnost ispitivanih osobina je utvđena PCA analizom, gde je ustnovljena visoka varijabilnost  za boju suvih i sočnih listova lukovice, dužini lista i boji lista. Ispitivani genotipovi su hijerarhijskim metodom razvrstani u 4 grupe i 19 genotipova koji ne pripadaju ni jednoj grupi ali su povezani sa ostalim grupama na različitom hijerarhijskom nivou. 

Ključne reči: crni luk, evaluacija, analiza glavnih komponenata (PCA analiza), hijerarhijska analiza grupisanja
