Raspberry plant - 'Dafne' cultivar

Abstract

A new a primocane raspberry cultivar named Dafne which produces glossy, strong red firm fruits is disclosed, with berries which are easy to pick due to low adherence to the plug. The new cultivar has the advantages of producing two crops per year, wherein the fruits equally ripen on the current season's cane in autumn and on the previous year's cane in summer.

[0016] FIG. 3 is a view showing the plant primocane internode length, cane colour and thorns.

[0017] FIG. 4 is a view showing the ripe fruit size and shape.

DETAILED DESCRIPTION

[0018] The following detailed description set forth the distinctive characteristics of the new variety Dafne. The performance of new cultivar for retention of its distinctive characteristics has been evaluated through successive asexual propagations by root cutting in the Applicant's setting in Trentino (Italy) under natural conditions in high tunnels. The growing was in soilless using coir as substrate.
