Biomorphological features of hybrid daylilies in the conditions of Southern Uzbekistan

The article presents the results of studies of the biomorphological features of promising daylily varieties (‘Carnival Song’, ‘Celebration Song, ‘Coral Beauty, ‘Matinata, ‘Soft Jazz’) in the conditions of the Karshi oasis. Significant differences in indicators were identified. In varieties ‘Heiloon Lace’ and ‘Red Velor, the number of flowers formed in the inflorescence and the diameter of the flower are larger (10.1 ± 0.6 and 11.0 ± 0.4, respectively), while in other varieties this figure is relatively less. In varieties ‘Heiloon Lace’ and ‘Red Velor, the number of buds formed on the rhizomes was less (0.85 ± 0.26 and 1.14 ± 0.14, respectively), while in varieties ‘Banbury Contrast’ and ‘Nile Crane’, which developed fewer flowers (respectively 6.1 ± 0.3 and 8.2 ± 0.4), by the end of the growing season more buds were formed. From this, it is concluded that hybrid lilies with the highest number of flowers have the lowest vegetative reproduction rate.
