Abstract
In many fern genera with horticulture value, frond crestation is a highly desirable trait in any normally non-crested frond species.
The knowledge on genetic control of the trait is valuable for a fern breeding program.
An inheritance study for crested frond in Asplenium (Emperor Group) and Nephrolepis Gretnae was thus performed.
The selfing progeny showed a discrete segregation.
The chi-square analysis revealed that the trait was under the control of dominant allele.
For the tetraploid Asplenium nidus mutant, a simplex status was confirmed.
Two complete dominant alleles of C and F with additive epistatic interaction were postulated to be responsible for frond variation of crestation patterns.
In Nephrolepis exaltata Gretnae, three groups of progeny were recorded.
An S allele which was incompletely dominant over an s allele was suggested.
