Two beet Lists focus grower choice

The new BBRO Recommended and Descriptive Lists of sugar beet varieties 2015, a two-pronged approach to providing growers with clearer variety choice guidance, were launched at an open day today (13th May). 

Only one new variety appears on the BBRO Recommended List for sugar beet 2015 which has been shortened to 10 varieties – down from 13 last year. In addition, one new variety has joined a second list; which the BBRO describes as its Descriptive List (DL) – varieties with a special recommendation for gene resistance to the AYPR strain of rhizomania or those tolerant to beet cyst nematode (BCN).

 

New variety Hornet, from breeder SES VanderHave, tops the Recommended List with a sugar yield of 101.9 per cent against controls, an adjusted tonnes figure of 102.0 per cent and sugar content of 18.5 per cent. The variety is best suited to the ‘normal sowing’ slot (see below for more info).

Maddox, bred by Syngenta, is the new addition to the DL List as a variety with ‘light tolerance’ to BCN and a sugar yield of 98.6 per cent against controls in uninfected trials.

 

Speaking ahead of the open days, chairman of the Recommended List board, Mike May said that one of the reasons for fewer varieties on the Recommended List 2015 than in previous years was because the system of assessing varieties for recommendation had tightened up.

*Below are the two Lists launched today, but more information will be published in the June edition of Farmers Guide out at the end of May.

AYPR and BCN varieties are not recommended for general use but only for where the relevant problem exists.
