AHDB Horticulture is highlighting the benefits of variety trials on new raspberry varieties funded by the levy board.
“Exciting work coming out of the latest summer fruiting raspberry variety trials means that soft fruit growers have increased access to delicious and profitable selections,” says AHDB Knowledge Exchange manager Scott Raffle. “Over the years, the UK Raspberry Breeding Programme has produced many competitive new varieties. The trial allowed the performance of a wide variety of selections to be compared to industry standards, Tulameen and Octavia.”
He says that of particular note were Squamish, Glen Carron, Glen Dee and two late selections from NIAB EMR, all of which he described as “outstanding.” Canadian variety Squamish produces unusually high yields for an early variety and has a low chilling requirement compared to Tulameen.
“Glen Carron (formerly 0485K-1) produces a very high quality raspberry that is consistently larger than Tulameen,” adds Scott. “It does have a high chilling requirement, but it could perform well when used in sequential plantings of cold stored long canes. Glen Dee offers a late season replacement to Octavia with very large berry size, high yields and high fruit quality.”
The trials also suggest that two NIAB EMR selections (EM6805/142 and EM 6804/81) could replace Octavia, producing higher yields than the long established standard. Two selections from Washington State University (WSU 1605 and WSU 1607) are also interesting.
“With more selections becoming available each year, growers are encouraged to seize the opportunity to compare some of the new outstanding varieties and selections with their own production systems,” stresses Scott, who recommends that growers download the AHDB Summer Fruiting Raspberry Variety Trial factsheet.
