Breeding new cereal varieties with improved frost tolerance is the ultimate solution to minimising the economic losses resulting from frost... Department of Agriculture and Food, Western Australia (DAFWA) frost researcher Ben Biddulph is leading the WA node of the ANFP and frost susceptibility ratings for wheat and barley in WA and will discuss how the ratings should be used at the 2015 Agribusiness Crop Updates... Dr Biddulph said across three years of the WA trials, it was found that wheat and barley varieties did differ in susceptibility to reproductive frost damage during booting and flowering and no varieties were frost tolerant...

A new mechanism to measure a cereal cultivars frost susceptibility has been developed by the Australian National Frost Program... 108.63: Ben Biddulph: And we actually go through every plot that 112.38: is flowering that day and we go through and tag between 30 and 60 heads in that particular 118: plot and we monitor those for the next 6 weeks, collect those heads and then take them back 122.64: to the laboratory and look at grain set and from that we can look at the reduction in 126.75: grain number and look at how the variety compares to other varieties at the same stage of development... 287.419: Ben Biddulph: But yeah it will be a while away I mean at 290.75: the moment growers can look forward to knowing the susceptibility of their varieties within 296.86: 2 to 3 years for wheat and barley but it is going to be a lot longer process for actually 301.669: developing frost tolerant per say and also trying to unravel those management impacts...

New frost performance value rankings enable varieties of wheat and barley to be compared for their frost susceptibility at the reproductive stage... Yield loss information to match the frost values will be determined in future research... Under severe frost (for example, -8 C) or multiple minor frosts (several nights of -2 C to -4 C) all varieties tested to date are equally susceptible, resulting in up to 100 per cent sterility in flowering heads...

"As a team we aim to better understand the complexities of frost in different environments, to determine whether there is genetic variation for frost tolerance in the field, to explore potential genetic and environmental interactions between regions, and to provide a focus on methods," Dr Biddulph says... "If there is variation - and preliminary results suggest that some genotypes may be more sensitive than others - we can assist breeding programs to develop varieties less sensitive to frost.".. While frost-tolerant crops are the ultimate goal, in order to get to that distant point we need a better understanding of how different frost events affect different cereals in different environments...

Wickepin grower Shane Hill is trialling several different management strategies to help mitigate frost risk and is taking a keen interest in the frost research being funded by the GRDC... With the exception of 2013 and 2014, when there was almost no frost damage on his property, Mr Hill says frost has continued to bite into his crop productivity and yields... In 2012, Mr Hill said he calculated that frost was costing his cropping operation about 0.8 tonnes/ha per year across their long-term yield average...
