Plant BreedingPlant Breeding by Example

Contextual examples linking theory with practice in plant breeding education.

Each of these educational resources uses a real-life example to illustrate plant breeding concepts and methods
Example 1 Plant introduction as a simple but valuable breeding method
William Erskine, Harry Nesbit and Marcal Gusmao
The introduction of crop germplasm as a method of crop improvement is as old as agriculture itself. This example describes the introduction of new cultivars into East Timor (Timor-Leste) by the Seeds of Life Project.
Example 2 Introgression of a rust resistance gene from rye into wheat
Ian Dundas, Diane Mather and Heather Bray
This example describes how wide crossing and chromosome engineering made it possible to transfer rust resistance from rye into wheat, without disrupting bread-making quality.
Example 3 Domestication of Tasmanian blue gum (Eucalyptus globulus)
Greg Dutkowski, David Pilbeam and Anthony Koutoulis
Domestication of wild trees for plantation forestry starts with seed collected from native forests. Trials are established and superior genotypes are selected for deployment and further breeding. These trials also provide useful information about genetic variation.
Example 4 Towards the development of canola quality Brassica juncea
Phillip Salisbury, Muhammad Javid and Wayne Burton
This example describes how changing the chemical composition of mustard seeds made it possible to develop a new oilseed crop for production in low-rainfall environments.
Example 5 Breeding for self-fertility in almonds
Michelle Wirthensohn
This example illustrates the importance of self-incompatibility and self-fertility in the breeding of a tree crop.
Example 6 Domestication genes in narrow-leafed lupin
Matthew Nelson, Dini Gaesalingham and Wallace Cowling
Mutations in specific major-effect genes confer a suite of traits that make narrow-leafed lupin suitable for cultivation as a crop.
Example 7 Breeding in a wind-pollinated grass species
Kevin Smith
A breeding program for perennial ryegrass illustrates the theoretical and practical basis of breeding methods that are used for wind-pollinated grasses.
Example 8 Using estimated breeding values in plant breeding
Kevin Smith and Peter Fennessy
What can plant breeders learn from animal breeding? This example discusses how methods that were developed for animal breeding can be applied in plant breeding.
Example 9 Customising barley for brewing styles
Heather Bray and Jason K. Eglinton
Knowledge of the biochemistry and genetics of barley enzymes is being used to develop barley varieties for specific markets.
Example 10 Screening and selection to improve disease resistance in faba bean
Rohan Kimber, Jeff Paull, Heather Bray and Diane Mather
Breeding for disease resistance in faba bean relies on exploitation of the genetic diversity from heterogeneous landraces and improved populations.
Example 11 Development of eucalypts for ornamental horticulture
Kate Delaporte and Heather Bray
The development of eucalypts for ornamental horticulture relies on understanding reproductive biology and the development of clonal propagation methods.
Example 12 Developing blackleg-resistant spring canola
Katrina Anne Light, Muhammad Javid and Phillip Salisbury
Two strategies are compared for transferring blackleg resistance from winter canola into spring canola.
Example 13 Development of submergence-tolerant high-yielding rice
David J. Mackill, Abdelbagi Ismail and Heather Bray
This example explains how marker-assisted backcrossing was used to introgress the Sub1 QTL from lower yielding lines into popular high-yielding rice varieties.
