Comment: Eradu background. ASWN for low rainfall areas and later sowings. Recently released ASWN variety (Supreme) has better rust resistance package. Strengths: Moderately resistant to Powdery mildew. Risks: Low falling number index (2) and susceptible to very susceptible (SVS) to Stem rust. Susceptible to Leaf rust, Stripe rust and RLN (P. quasitereoides and P. Neglectus).

Comments: Also known as EGA Bonnie Rock. Aroona background. Recommended in Agzone 1 & 4 because of rust package. Intermediate sensitivity to frost. Strengths: Low risk for black point. Risks: Very susceptible (VS) to stripe rust, S to Leaf rust, Powdery mildew, Flag smut, RLN (P. quasitereoides and P. Neglectus) and CCN. Stem rust resistance level has been downgraded to moderately susceptible to susceptible (MSS). S to Septoria tritici blotch

Comments: An AH variety for med to high rainfall areas. Strengths: Good rust package with Stripe Rust -moderately resistant (MR*), Stem Rust - resistant to moderately resistant (RMR) and Leaf Rust (MR). Low screenings. Maintains falling number after pre harvest rain (5p*), similar to Yitpi. Risks: S to Septoria tritici blotch, Powdery mildew, Flag smut and Crown rot. Maturity like Magenta so not suited to low rainfall areas/later plantings.

Comments: Wyalkatchem background. Suited to late May, early June sowing. Strengths: Useful resistance to CCN (RMR) and stem rust (MR). Risks: Powdery mildew -SVS, Black Point (MSS), Septoria tritici blotch and Crown Rot are S. Now S to Leaf rust. Corack is less suitable to higher rainfall zones because of its susceptibility to Black Point and Leaf rust. Sensitive to frost (Wyalkatchem equivalent).

$3.00

Comments: Wyalkatchem background with higher grain yields. The benchmark variety for yield in WA. Wide adaptation across regions and soil types. Intermediate sensitivity to frost. Strengths: Better disease resistance than Wyalkatchem. Superior to Wyalkatchem for falling number after pre harvest rain. Boron tolerance. MR to stem rust and Common bunt and RMR* stripe rust. Risks: High yielding so may require increased nitrogen fertilisation to prevent protein dilution. S to Septoria tritici blotch, Flag smut and Crown rot.

Comments: High yielding wheat suited to early to mid-sowing opportunities. A good disease package so suitable for wheat on wheat situation Strengths: Yields similar to Wyalkatchem, with long coleoptile, good resistances to Stem rust (RMR), Leaf rust (R*) and Yellow spot (MR). Excellent early vigour. Risks: Similar falling number risk (3p) to Wyalkatchem, so not suited to south coast. Common Bunt S.

Comments: Favoured in eastern wheatbelt region. Strengths: Yields comparable to Wyalkatchem, good aluminium tolerance. Less sensitive to frost (similar to Yitpi). Risks: Stem rust (SVS) and stripe rust (VS). Powdery mildew, Common bunt and RLN (P. quasitereoides formally P. teres) are 'S'. Flag smut and RLN (P. neglectus) are 'SVS'.

$1.92

Comment: Machete background. Strengths: Suitable for wheat on wheat system due to resistances to yellow spot and ease of stubble management. Acid soil tolerant and low screenings. RMR# to Leaf Rust however maybe more susceptible to newer strains of rust. 'RMR' to Common bunt. Risks: Short coleoptile length and less competitive with weeds due to poor early vigour. Susceptible to Stripe rust, CCN and Crown rot. 'SVS' to Powdery mildew and Flag smut. Risk of low falling number with pre harvest rain. Sensitive to frost (Wyalkatchem equivalent).

Comment: Spear background. Strengths: Variety popular in southern areas due to lower frost susceptibility and longer maturity. Maintains falling number with pre-harvest rain. Large grain size, long coleoptile, is tolerant to CCN and Boron. Risks: Stem rust (S) and yellow spot (SVS). Not suited for wheat on wheat.

Comments: Calingiri and Wyalkatchem background. Offers yield and disease improvements on Calingiri. Intermediate sensitivity to frost. Strengths: Rust package better than Calingiri. Yellow leaf spot and S. nodorum resistance (MRMS) better than Calingiri. Risks: Powdery mildew (SVS). CCN and Crown rot are 'S'.

Disease ratings

VS = Very susceptible, SVS = Susceptible to very susceptible, S = Susceptible, MSS = Moderately susceptible to susceptible, MS = Moderately susceptible, MRMS = Moderately resistant to moderately susceptible, MR = Moderately resistant, RMR = Resistant to moderately resistant, R = Resistant. No score '-' = no rating is currently available. p = Provisional assessment. / = Scores separated by ‘/’ indicate the response to the 'currently predominant' and 'alternate' strains of stem rust existing in WA. * = Some races in eastern Australia can attack these varieties. # = May be more susceptible to the new leaf rust pathotype. ( ) = Higher disease at some sites. Combined RLN ratings from DAFWA, SARDI (^), DPI Vic and DEEDI data. CCN ratings from SARDI data. Wallwork and Zwer (2016) Cereal Variety Disease Guide 2016, Factsheet Feb 2016. R=resistant - nematode numbers will decrease when this variety is grown. MR=moderately resistant - nematode numbers will slightly decrease when this variety is grown. MS=moderately susceptible - nematode numbers will slightly increase when this variety is grown. S=susceptible - nematode numbers will increase greatly when this variety is grown. Crown rot ratings from SARDI data 2009-2014 (Butt, Edmondson, and Wallwork), Qld data 2009-2014 (Bottomley, Herde, Neate, Percy, and Walters) and DPI NSW data 2013-2014 (Simpfendorfer).
