Nuclear DNA Content, Selected Morphological and Anatomical Traits of Narcissus Cultivars and Breeding Clones

The genus Narcissus belongs to the family Amaryllidaceae. This has been subject of numerous cytological and cytometric studies have shown enormous variation in terms genome size, ploidy level, even basic chromosome number. numbers are 5 or 7, but 10, 11, 12 recorded as well. Most narcissus cultivars euploid tetraploids. There also triploids. Some aneuploid such tetraploids triploids, with missing chromosomes possessing additional chromosomes. Due their very complex parentage, various not found species. In this publication, we present a study on size assessment likely level 38 breeding clones relation selected morphological traits information parental forms. For first time, Polish were an evaluation. Perianth diameter, leaf length, width evaluated rated notes according descriptor International Union for Protection New Varieties Plants. Stomatal density stomata length measured using light microscopy. Analysis was carried out flow cytometry. three genotypes, number counted. Our results lead general conclusion that studied nuclear DNA content can be useful determining possible narcissi. origin forms narcissi helpful However, clear confirmation requires verification preferably karyotyping. obtained prelude further studies.
