Sarah Tropp, trials officer for Meiosis, which introduces new cultivars to the fruit industry, and a Nuclear Stock Association (NSA) member, told HDC News this month that the variety offered new hope for raspberry growers who have found that fruit quality varies considerably between clones.
She said: "The fruit quality of some clones is very inconsistent, leading to increased harvest labour costs and a lower than expected class 1 yield."
Seven clones were included in the trials - four from the UK and one each from Germany, Holland and the USA. The trial assessed the quality over two harvest seasons and found that the Dutch and German clones performed the best.
The NSA is now sourcing its high health Tulameen material solely from the Dutch clone held at Naktuinbouw, the Netherlands inspection service for horticulture, which is propagating stock for growers.
