Artificial hybrids between the inbreeding species B. goniocarpa Sond. & F. Muell.(n = 4) and outbreeding B. dichromosomatica C. R. Carter var. dichromosomatica (n = 2) have been produced. Morphologically, the hybrids were essentially intermediate between the parental species. Cytological investigations showed that the total length of mitotic metaphase chromosomes for the B. dichromosomatica haploid set was 1.33 times that of the B. goniocarpa set. Chromosomes derived from the parental species…

Chromosomal Evolution in the Genus Brachyscome (Asteraceae, Astereae): Statistical Tests Regarding Correlation Between Changes in Karyotype and Habit Using Phylogenetic Information
TLDR
The correlations between the dysploidal reduction in chromosome number and the increases in mean chromosome length, length heterogeneity and asymmetry in karyotype can be attributed to this mode of chromosomal change.
Molecular phylogeny ofBrachycome (Asteraceae)
TLDR
Intrageneric relationships in the genusBrachycome were investigated by the comparison of nucleotide sequences of the chloroplast genematK, and circumscription of superspecies based primarily on fruit morphology is not fully supported.
Exploring adaptation in a key Australian genus Brachyscome through experimentation
TLDR
This paper presents the results of three experiments on the basis of which three hypotheses, Habitat Specialization Versus Performance in Australian Alpine Daisies and Range Size Hypothesis were chosen, were determined.

Internal transcribed spacer sequence analyses indicate cytoevolutionary patterns within Brachycome Cass. (Asteraceae)
TLDR
The sequences of the Internal Transcribed Spacer regions (ITS1 and ITS2) within the genes coding for cytoplasmic ribosomal RNAs on the A chromosome complement of 34 members of the higher plant genus Brachycome have been compared to support the suggestion that the number of chromosomes reduced in several independent Brachy Come lineages during speciation.

TLDR
It is suggested that the evolution of the races can be related to the increasing aridity of the Late Pleistocene and Recent geological epochs.
The cytology of Brachycome line ariloba
TLDR
In hybrids there is a marked difference or asynchrony in the condensation patterns of the chromosomes from the two parental sources, and suggests that there are segmental homologies between the two lineariloba chromosomes and three of the four campylocarpa chromosomes.

TLDR
The present taxonomy of the group requires revision, taking into account cytological data, and it is inferred that x = 9 is the primitive base number in the group.

TLDR
The overall objective is to show that PIO's reflect the likelihood of sufficient pollen grains reaching each stigma to result in maximum seed set and suggest that PI O's are integrated with other facets of a plant's breeding system.
