Table showing the predicted flowering dates in three regions using the Flowering Calculator.. The successful adoption of this strategy hinges on matching variety to sowing time to maximise growth and to minimise the likelihood of frost damage after flowering - and also to minimise the impact of hot weather and terminal drought during grain fill... The Flowering Calculator is a tool that enables an adviser or grower to compare flowering dates relative to the risks of frost and the likelihood of experiencing water stress during grain development...

Location should be an important consideration in wheat varietal selection for growers in the northern region cropping belt... Dr Martin said the research has found that varieties generally flower in the same order across years and sowing times, but there are some important exceptions... Suntop is a variety that seems to behave differently in the northern environments in that it is a couple of days earlier than Gregory in places like Wagga and Narrabri, but when you get up into Central Queensland it can be 10 days, and in one experiment 20 days, earlier than Gregory ," Dr Martin said...

There is simply nothing in the domesticated gene pool that can provide in-between flowering times... During 2014, a breakthrough was made in Dr Nelson's laboratory by a 22-year-old GRDC undergraduate honours student, Candy Taylor, who at the time was completing the fourth year of a genetics and breeding undergraduate course at the University of WA... "In early-flowering plants that do not require vernalisation to flower, the FTc1 (flowering-time) gene was expressed at high levels at all times and throughout the plant," Ms Taylor says...

Bonnie Hargreaves was awarded a GRDC undergraduate honours scholarship to investigate black spot in field peas to better understand how to breed for resistance.. Individual plants were found with resistance to black spot and early flowering times suitable for southern Australia: " the correlation between the two traits indicated that later flowering times meant better resistance to black spot," she says... Professor Kadambot Siddique, director of the UWA Institute of Agriculture, says that while moderate resistance to black spot has been found in existing field pea germplasm, this new breeding method coupled with new genomic technology could speed up genetic improvements for black spot resistance and other desirable traits...

" Adapting wheat to future warm and dry climates - improved simulation of flowering and tillering.. Extreme heat events in southern Australia in 2004 and 2009 and most recently in October 2014 have raised questions about the likelihood of such events in the future and their consequences for cropping systems.. CSIRO research is investigating how current Australian wheat varieties will fare developmentally under future climate change scenarios...

Variation in flowering behaviour plays a major role in adapting cereal varieties to different growing regions and diverse climates... The lines can be grown across Australia to identify the optimal flowering behaviours for different regions, which can then be targeted in breeding programs... In summary, the project succeeded in producing the most comprehensive set of near-isogenic wheat and barley lines for studying flowering behaviour and phenology...
