one of the micropylar nuclei and one of the chalazal, thus producing an
apomictical sac. That the fusion should take place between adjacent quartets is
excluded, since segregation would result, unless a perfect state of homozygosity
is present ...

The mechanism of creative evolution
These hybrids, also being apomictical, became permanently fixed at once and
bred true, much to Mendel's disappointment. It is probable that much of the
extreme variability in Hieracium and in the Caninae roses is also due to this
faculty for ...
Charles Chamberlain Hurst, 1932
In the discussion of the origin of the hybrid and apomictical collective species of
the Caninae, their phytogeographic range over Europe and a thin mountainous
strip of Asia is indicated. The forms included in the cytological study represent the
...

... with that of the Pleistocene Ice Sheet at its maximum southern and eastern
limits of influence. 2. These species, so far as they have been tested genetically, (
12) appear to be facultatively apomictical with irregular but partly fertile pollen.

Since the supersection Canina and the allied Syn- styhe include both sexual and
apomictical microgenes, and further since the former is the more primitive and
normal state in the Rosacea, it is a reasonable assumption to make that the ...
For instance, Lundstrom (1909), Dingler (1908) and myself (Harrison, 1920) have
all demonstrated that the majority of European polyploid roses are apomictical.
Furthermore, Tackholm (1922), my colleague Dr. Blackburn and myself ...

Experiments in genetics
so far tested (16 forms) are apparently facultatively apomictical when planted
side by side and seeded naturally with uncovered flowers, thus confirming to
some extent Tackholm's (1920) conclusion that they may represent ancient F,
hybrids ...
Charles Chamberlain Hurst, 1925
Erigeron annuus prefers rich, moist situations ; E. strigosus is a plant of dry,
barren areas Apomictical forms of both annuus and strigosus have occured,
some of which seem to have been very widespread. Weed strains of both species
have ...

... apogamy of other species, a further manifestation of the powers of heterosis
stimulating, in the one case cells from the soma, and in the other the germ-cells,
to an enormously exaggerated development ending in apomictical reproduction.
