Diversity in flower characteristics and chromosome numbers of Rain Lily (Zephyranthes spp.)
Year: 2024
Type: article
Abstract: The study examined the flower characteristics and chromosome numbers of twenty rain lily genotypes with different origins. The bulbs of investigated genotypes were grown sequentially in an experimental garden under net-house conditions at the Vietnam National University of Agriculture. The data was collected for flower parameters including flower size and color, flower longevity, lengths of stamen, pistil, and anther, and the number of chromosomes. The results showed that the rain lily genotypes exhibited diversity in flower color and flower diameter, making advances for bedding flowers and landscaping. Furthermore, a wide range of chromosome numbers (from 2n = 18 to 2n =54) was found among the genotypes from 2n =18 in genotype D21 to 2n = 54 in genotype D6. The new chromosome numbers of Z. atamasco (2n = 22), Z. ajax (2n = 28), Z. candida (2n = 30), Z. rosea (2n = 28), and Habaranthus robutus (2n = 18) from Vietnamese genotypes and new hybrids were updated. The information will be valuable for the breeding programs of this species.
