>Our research focuses on understanding how genetic material is exchanged between two different types of azaleas, one with two sets of chromosomes (diploid) and the other with four sets (tetraploid), in regions where they coexist. Additionally, it aims to explore how frequently new hybrid azaleas with either three, four, or five sets of chromosomes (triploids, tetraploids, and pentaploids, respectively) are created in these areas.
In simpler terms, the study investigates the interaction between two different types of azaleas with different numbers of chromosomes and how this interaction leads to the creation of new azalea hybrids with varying numbers of chromosomes.
The study seeks to answer three key questions:
-
How often do triploid hybrids produce viable offspring?
-
How frequently are tetraploids created due to an unreduced gamete from a diploid azalea fertilizes a tetraploid azalea?
-
How frequently are pentaploids created due to a fertile triploid azalea producing an unreduced gamete that fertilizes a tetraploid azalea?
