Plant Variation and Evolution
The use of molecular markers in the study of the reproductive behaviour of
apomictic plants Studies of population variation in reproductive behaviour have
been revolutionised by the used of genetic markers, and provide the potential for
the ...
an unreduced egg cell from the apomictic hybrid (2n = 35) was fertilized by a 21-
chromosome gamete, produced by a hexaploid interspecific hybrid (2n = 42),
involving P. purpureum. The off-type plants were obligately and facultatively ...

Reproductive Versatility in the Grasses
Progress in breeding apomictic grasses Successful breeding of apomictic
species is a relatively recent achievement and thus far only a few artificially bred
cultivars of any apomictic crop have been released. For many years the only
source of ...

Principles of Plant Genetics and Breeding
Theoretically, in an apomictic system, hybrids could be maintained indefinitely if
the first division restitution (FDR) events discussed above did not occur. Most
likely, apomixis will be first utilized to stabilize genetic combinations that
otherwise ...

Genetic control of self-incompatibility and reproductive ...
the developmental pathway of those nucellar cells which surround structures
derived from apomictic and sexual processes is clearly distinct as these cells do
not give rise to other structures and eventually senesce. Environmental effects ...

The Flowering of Apomixis: From Mechanisms to Genetic ...
In model 2, apomixis is active in plants with the Aa association of alleles. The aa
genotypes are sexual. If Rn is the frequency of aa genotypes (sexual) and Qn is
the frequency of Aa genotypes (apomictic), frequencies in the next generation (n
...

Tropical Forage Plants: Development and Use
Traditionally, apomictic breeding was merely the selection and increase of
superior, naturally occurring, apomictic ecotypes. Most cultivars of apomictic
tropical grasses used today were obtained in this manner. An excellent example
is guinea ...

Brachiaria: Biology, Agronomy, and Improvement
Other crosses include B. decumbens (2x, sexual) pollinated by B. humidicola (4x,
sexual accession H31); H31 x B. decumbens or H31 x B. brizantha (4x, apomictic
); and H31 x B. ruziziensis (4x, sexual). Seeds will be germinated, and the ...

Apomixis: Exploiting Hybrid Vigor in Rice
Synthetic approach: Since the genetic control of basic components of gametogen
- esis and apomixis is not well understood (see next section), it may be premature
to recommend the synthetic approach to obtain apomictic rice. Knowledge ...
