LATEST LENTILS - Two new lentil varieties will be commercialised this year
through the GRDC-funded Co-ordinated Improvement Program for Australian
Lentils.
 
CIPAL402, a green lentil, is suitable for medium rainfall regions in WA as a
replacement for Matilda and will be available to growers in 2007.
 
The new variety has a yield advantage over existing red lentil varieties in
WA and has improved ascochyta blight and botrytis grey mould resistance,
vigour and larger seed size compared to green lentil variety Matilda.
 
CIPAL402’s seed is about 30 per cent larger than Matilda’s, improving
opportunities for the new variety in markets which value larger seed.

TOUGH LITTLE MALLOW – Small flowered mallow seed can be transmitted through
sheep and therefore make its way back into the seed bank, according to new
research.
 
GRDC-supported researcher Pippa Michael, of the University of Western
Australia, found the hard seed coat enabled it to survive digestion and
prevented the death of the seed’s embryo.
 
“The small seed size may also allow it to be transmitted through the sheep’s
digestive system and help minimise the impact of sheep mastication and
rumination,” Ms Michael said.
 
“From a management perspective, sheep could be used as a control option only
when the small flowered mallow seed is not mature during consumption.”

SUBSOIL SURVEY – Growers are encouraged to complete a survey to help
determine research priorities for a new project, Managing Hostile Subsoils,
part of a GRDC initiative addressing subsoil constraints which restrict root
growth and uptake of water and nutrients.
 
Managing Hostile Subsoils aims to assess the extent and impact of subsoil
constraints in the WA wheatbelt. In the next four years it will conduct
targeted, relevant and practical research and inform growers on management
techniques.
 
Researchers from the University of Western Australia and the Department of
Agriculture are partnering the Mingenew-Irwin Group and Corrigin Farm
Improvement Group in the project.
 
The survey questionnaire was distributed through the WA No-Till Farmers’
Association newsletter and to other grower group members.
