Accelerated breeding for a changing environment: genomic and physiological profiling of newly generated polyploid trees. Global climate change threatens the health and productivity of forests and plantations. Because tree breeding is slow, elite trees cannot be adapted rapidly to new environments. A new procedure for accelerated tree breeding has been developed by the industry partner. The procedure, termed polyploidisation, increases DNA content and produces novel traits that can improve plant ....Accelerated breeding for a changing environment: genomic and physiological profiling of newly generated polyploid trees. Global climate change threatens the health and productivity of forests and plantations. Because tree breeding is slow, elite trees cannot be adapted rapidly to new environments. A new procedure for accelerated tree breeding has been developed by the industry partner. The procedure, termed polyploidisation, increases DNA content and produces novel traits that can improve plant growth and resilience. Polyploidisation is a natural force in plant evolution and its routine application for tree breeding has much potential. Using diverse approaches, we will investigate how newly synthesised polyploid tree species perform under heat and drought stress.Read moreRead less
Potential of Corymbia torelliana hybrids for hardwood forestry and investigation of their seed dispersal by Trigona bees. Cadaghi (Corymbia torelliana) and their hybrids with spotted gums (C. variegata complex) have enormous potential for plantation forestry. These hybrids have many excellent features that make them exciting as hardwood species, such as resistence to disease, tolerance of marginal environments, good wood properties, and fast growth rates. This project will create hybrids between ....Potential of Corymbia torelliana hybrids for hardwood forestry and investigation of their seed dispersal by Trigona bees. Cadaghi (Corymbia torelliana) and their hybrids with spotted gums (C. variegata complex) have enormous potential for plantation forestry. These hybrids have many excellent features that make them exciting as hardwood species, such as resistence to disease, tolerance of marginal environments, good wood properties, and fast growth rates. This project will create hybrids between Corymbia torelliana and spotted gums to identify hybrids which are suitable for sustainable wood production on marginal agricultural lands.
An unusual feature of Cadaghi is that native Trigona bees disperse their seeds. This project will investigate this unique seed dispersal mechanism and identify features of hybrids that are not attractive to bees. This will prevent environmental problems by preventing hybrids from dispersing seeds, becoming weedy and harming the Trigona bees.
