New wheat variety Gascoigne shows promise, flexibility

09 Nov, 2008 03:00 AM
Although designed for medium rainfall zones, trial work with the new wheat variety Gascoigne is showing promising results across a spectrum of climatic conditions.

The AWB Seeds variety has shown good quality traits, such as large seed size and low screenings which may even make it attractive for other regions, especially in light of the tight finishes currently being seen across south-eastern Australia, where the large seed size may prevent excessive screenings levels caused by the dry conditions.

Its yield potential is also a positive – in trials in NSW it was consistently the highest yielding line, beating varieties such as Chara, Janz and Drysdale.

It has also yielded well in Victoria and SA, beating Chara and Kellalac and also yielding slightly better than the most popular variety through southern Australia – Yitpi.

There is a provisional quality rating of APW for the variety, although further tests are being conducted.

Breeders are confident APW will be the lowest classification the variety achieves.

Disease-wise, the variety has improved resistance to fungal diseases than do a number of similar varieties.

It is resistant to stripe and leaf rust and moderately resistant to stem rust.

It has a new line of resistance to the rusts and does not rely on the outdated Yr17 resistance gene.

Gascoigne is of mid season maturity and performs best if sown in mid to late May in southern NSW or mid May to early June in South Western Victoria or SE South Australia.

It flowers slightly earlier than Sunbri and 2-3 days after Chara.
