DBA Artemis

DBA Artemis

Release by Dr Jason Able at Roseworthy Sept 11,2019

Variety Snapshot

  • DBA Artemis has a small yield potential advantage over DBA Aurora (but region dependent)
  • Screenings levels and disease profile are comparable to both Aurora and Spes
  • Artemis is well adapted for production in the southern wheat growing areas of Australia (SA & Vic)
  • Well suited to early-sowing (early May) or mid-sowing (mid-late May)
  • Is tolerant to a range of common grass and broadleaf herbicides
  • Is WQA approved and is classified ADR in Southern Australia (SA & Vic)

Breeder Comments

Trial data to date suggests that DBA Artemis will be at least comparable or slightly better than Aurora in SA’s Yorke Peninsula and the West Wimmera, respectively. There does not appear to be any significant yield advantage for the broad MN area with this new variety, when compared to Aurora, based on long-term NVT data (Table 1).

The origin of DBA Artemis is from the combination of two fixed lines. The maternal parent of these is Menshia54/2*Kalka/Worrakatta//Tamaroi/Kalka/Kalka/Tamaroi, which was crossed to the paternal parent Kalka*4/Tamaroi.

Risk Factors

Yield vs Protein: As with very high yielding varieties such as DBA Aurora, DBA Artemis may also result in lower levels of protein due to its high yielding performance. Therefore an N management strategy should be implemented by growers that focuses on both grain yield and protein.

Table 1. DBA Artemis yield performance in southern national variety trials (NVT) averaged across three years of trials (2016-2018). Data for each variety is expressed as a % above or below the area mean. Where * is data from 2017-2018 only.

Table 2. DBA Artemis disease resistance ratings compared to current commercial varieties in the southern region. Abbreviations as follows: YLS (Yellow Leaf Spot), Prn (P. neglectus), Prt (P. thornei), CCN (Cereal Cyst Nematode); CRR (Common Root Rot), CR (Crown Rot). This is the 2018 consensus ratings from NVT. Subscript P stands for a provisional rating.

DBA Spes

Dr Jason Able released the new variety Spes at the Roseworthy and South East  crop-walks in spring 2018. Dr Able states that DBA Spes assists in alleviating some of the risk associated wit growing durum and improves durum’s fit in the farming system rotation.

Variety Snapshot

  • DBA Spes maintains a high relative yield
  • Slightly superior resistance to stem rust
  • Equivalent or slightly superior disease resistance package to other diseases
  • Acceptable protein average
  • Delivers improved grain size over older varieties.
