The Phenotypic Characters of the F1 Generation Derived from Hemerocallis spp Crossing

Abstract

Hemerocallis spp is a perennial plant that forms clumps and is commonly used as a landscape and potted plant. This plant belongs to the Liliaceae family and has a perfect flower. This research aimed to examine the morphological diversity of F1 from the Hemerocallis crossing. This research was conducted from August 2020 to October 2021 in Cipanas District at the elevation of 1100 m asl. Seven F1 progenies from a crossing of “After the Fall” (AF) and “Happy Return” (HR) were used as the plant materials, namely 20.008, 20.012, 20.018, 20.019, 20.021, 20.022, and 20.024. Randomized complete block design (RCBD) was employed in this experiment. The results showed that there were quantitative and qualitative variations in morphological characters in each progeny. Flower diameter, petal length, sepal length, number of florets, number of leaves, and leaf length showed similar characteristics to those of the male parent (HR). Stamen length, petal width and leaf width showed the combined characters of the two parents. Flower color characters were similar to the female parent (AF), while the flower shape, namely circular, triangular, recurved and ruffled follows the combined characteristics of the two parents.
