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...

For over a century Australian wheat breeders, starting with the pioneering efforts of William Farrer, have selected and channelled natural variation to produce wheats with flowering behaviour (phenology) suited to Australian growing conditions... The project will first survey the extent of diversity in the key genes that control flowering behaviour through the Australian wheat breeding pedigree and assess the historical contribution of this variation to successful adaptation to Australian conditions... In summary, the project will provide valuable genotype information and deliver new genetic resources to Australian wheat breeders...

For most parts of the northern grains region, there is a very high probability that crops flowering in July and August will be lost to frost damage (Figure 1)... In the northern grains region conflicting climatic influences including moisture availability and high temperatures severely constrain the timing of winter cereal flowering and grain filling if yield potential is to be maximised in face of frost risk (Figure 3)... In the absence of frost resistant winter cereals genotypes, our main strategy to minimise crop losses while maximising yield potential is to aim to achieve crop flowering and grain filling in the short window of opportunity following the main frost risk period (Figure 3)..

Dry or "early" seeding of wheat, when undertaken at appropriate times and seasons, should yield a modest additional profit... The economic outcomes are computed in a particular hypothetical case, and summarised using Prospect Theory... Taking account of prior summer rain, a criterion level of moisture after 31 March which constitutes the break has been computed for all years from 1976 onwards...

Spread of flowering dates of dry sown crops can be successfully achieved through varietal choice and adjusting sowing order of the wet sown crop according to the flowering prediction of the dry sown crop... The aim of this paper is to discuss possibility of using varietal differences in phenology mechanisms to achieve a desired spread of flowering dates after dry sowing... The data were used to estimate: 1) spread for flowering dates of varieties across germination dates, 2) the range of achievable variation through varieties for given sowing dates...

Sowing time is a major determinant of crop yield because, in partnership with the variety chosen, it determines the timing of key development stages and the environmental stresses at these key stages... Flowering time is a key factor in adapting a crop to an environment... Varieties differ in intrinsic earliness, a measure of how quickly they flower under optimum conditions...

Helps plan sowing dates to spread the flowering window and reduce climatic risks - By Nicole Baxter.. A new online decision-support tool has been designed to help Western Australian growers select wheat varieties and sowing dates to maximise crop growth while minimising losses from frost and heat... Using the tool involves selecting a location, choosing up to three wheat varieties for comparison, changing the sowing date and then checking the flowering dates predicted...

The majority of current wheat varieties need to be sown in the first half of May in order to flower during the optimal period for yield in most environments, which unfortunately coincides with the period of recent rainfall decline... Growers wishing to maximise farm water-use efficiency need to adopt strategies that will allow them to get as much of their wheat crop as possible flowering during the optimal period in their environment... The article reports results from several experiments conducted across southern Australia and farmer experience investigating the potential for earlier sowing to increase wheat yields in the face of autumn rainfall decline...
