Livingston is one of few varieties that has moderate tolerance to root lesion nematodes (RLN), along with other desirable features... The researchers concluded that where Pt combines with high levels of crown rot (a common scenario), yield losses can be exacerbated if varieties are susceptible to Pt. Instead of a 10 per cent yield loss from Pt in a susceptible variety it could be 30 to 50 per cent if crown rot is combined with a Pt-intolerant variety...

NGA have been involved in 22 field trials since 2007, in collaboration with Steven Simpfendorfer I&I NSW, evaluating the impact of crown rot (CR) on a range of winter cereal crop types and varieties... During 2007 & 2008 a common series of 5 bread wheat varieties, 4 barley varieties and 1 durum were evaluated in all 18 trials... 2. Less apparent range in variety Pt tolerance than seen for bread wheat Figure 5 shows the variety yield performance compared to EGA Wylie for all varieties evaluated in both 2008 and 2009...

At a trial site near Yallaroi in 2012, a range of crops and varieties were grown where performance was evaluated in strips with contrasting starting levels of Pt ... All varieties evaluated in all 9 trials except CICA0912 (only 6 trials).. Differences in Pt populations following a range of crops assessed at two sampling times during the fallow, Yallaroi 2012..

Variety choice influences profitability.. Tom Giles, trial operations manager, GRDC, says the study also shows that in some regions selecting a wheat variety classified as Australian Hard (AH) instead of Australian Premium White (APW) could reduce growers' profitability... " the analysis demonstrates why it is important for growers to carefully consider their choice of varieties," Mr Giles says...

Remember APR when selecting varieties.. Varieties carrying APR genes are protected from rust during the post-seedling stage of crop development, typically between tillering and booting (growth stages 20-49)... PHOTO CAPTION: Northern region grain growers are being reminded to consider adult plant resistance (APR) to fungal diseases such as stem, stripe and leaf rust, when retaining seed this harvest for next year's crop...

Varieties carrying APR genes are protected from rust during the post-seedling stage of crop development, typically between tillering and booting (growth stages 20-49)... Professor Robert Park, from the Australian Cereal Rust Control Program, said because the timing and effectiveness of APR varies from gene to gene, it varies from variety to variety depending upon which gene(s) are present...

Although the trials were not designed to focus on nematodes, a convincing trend was apparent after 2008 that indicated the root lesion nematode Pratylenchus thornei (Pt) was having a frequent and large impact on wheat variety yield... During 2007 & 2008 a common series of 5 bread wheat varieties, 4 barley varieties and 1 durum were evaluated in all 18 trials (NB only 17 yield results are presented as barley varieties were heavily damaged by emus at 1 site in 2008)... 2. Less apparent range in variety Pt tolerance than seen for bread wheat Figure 5 shows the variety yield performance compared to EGA Wylie for all wheat varieties evaluated in both 2008 and 2009...

There are consistent varietal differences in Pt resistance within wheat and chickpea varieties.. Yield losses in chickpeas of up to 20% have also been measured in DAFF QLD trials.. Recent research has shown that in addition to resistant crops, there are consistent and useful levels of difference in resistance within key 'susceptible' crops such as wheat and chickpeas...
