Little Ponton RTC Updates May and March 2017

Little Ponton Update (05/05/17) - Edition 3
Greh Hopkinson & Sally Morris

Freiston – One of the cleanest new varieties at Little Ponton RTC

Spring Wheat – Chilham (above) has established significantly worse than older varieties such as KWS Alderon

Winter Wheat

All the Winter Wheat varieties at Little Ponton have reached GS32 with little difference between the varieties in terms of growth stage. Due to the dry weather disease levels are relatively low in general, especially in terms of Septoria. The varieties with the highest levels of Septoria are KWS Santiago and Leeds. However, some of the recently recommended varieties have higher levels than expected, especially LG Sundance and Marlowe.

Levels of yellow rust are also generally low except on the most susceptible varieties such as Reflection and Belgrade. Surprisingly there are also low levels of yellow rust on more resistant varieties such as Graham and Shabras. Also, KWS Santiago has no yellow rust at all, despite its low resistance score which may suggest a change in the yellow rust population.

Mildew levels are also generally low, with only Leeds, KWS Santiago, Costello and Revelation having significant levels.

Of the newer varieties on show at Little Ponton KWS Siskin, Freiston and Bennington all look particularly clean at the minute. They also have slightly higher GAI scores compared to other varieties.

Spring Wheat

All the Spring Wheat and Spring Barley plots have now been drilled at Little Ponton with all varieties at the early tillering stage. Generally the older varieties have established the best, with Propino and Concerto having the highest GAI of the Spring Barley varieties. Mulika, KWS Kilburn and KWS Alderon have also developed significantly faster than the new varieties of Cochise and Chilham.

Greg Hopkinson & Sally Morris

The Winter Wheat plots at Little Ponton are all at the late tillering stage, somewhere between GS23 and GS25. No variety has quite reached GS30, however KWS Crispin, KWS Siskin and Costello are not far away.

Generally the level of disease is low in all varieties with no yellow rust being found even in susceptible varieties such as Reflection, Diego and Zulu. Septoria tritici can be found on older leaves, however this is also at relatively low levels. Of the currently grown varieties Costello, KWS Siskin, KWS Crispin and Spyder are particularly clean. In comparison; the highest levels of disease can be found in JB Diego, Leeds and Belgrade.

At Little Ponton we also have plots of some of the new varieties recently added to the recommended list. The varieties which look particularly promising at the minute are Marlowe, LG Sundance and KWS Zyatt; all of which are free from disease and well established with relatively high GAI’s.

The spring cereal plots have recently been drilled, with a few of the plots just starting to emerge. These spring varieties will be assessed next month once they are fully established.
