Abstract
Hemerocallis cv. ‘Autumn Blaze’ plantlets generated in quantity on semi-solid media from tiny nodules aseptically maintained and multiplied in liquid were raised to maturity. Comparisons were made between phenotypic characters of flowering plants derived from culture and a non-cultured clonal population which included the plant from which the primary explant of the material was taken. Plants were pheno-typically identical. Within the limits of the cytological techniques used, it was not possible to disclose differences between karyotype of root tip cells of plants produced via aseptic culture and those that had not been cultured.
