Raspberry plant named ‘HFG 1714’

A new and distinct cultivar of primocane-fruiting raspberry named ‘HFG 1714’. The new variety reliably provides balanced heavy crop load on both primocanes and floricanes with very large, conical, extremely firm, subacid, pinkish-red colored berries suited for the fresh market. Plants possess high vigor, high number of spawn, and exceptional bud break in the floricane cycle.

Description

Latin name of the genus and species of the plant claimed: Rubus idaeus L.

Variety denomination: ‘HFG 1714’.

BACKGROUND AND SUMMARY

The new primocane-fruiting raspberry cultivar designated as ‘HFG 1714’ is shown herein. Botanically known as Rubus idaeus L., the new variety ‘HFG 1714’ resulted from a hand-pollinated cross of female parent ‘PBBrasp1348’ (U.S. Plant Pat. No. 29,368P2), and the male parent ‘1338’ (unpatented) both of which are genotypes from the same breeding program. Hand-pollination from this directed cross occurred in April 2015. Seeds from this population were harvested, cleaned, germinated, and subsequently established as seedlings in spring 2016 in Watsonville, California, Santa Cruz County, USA.

‘HFG 1714’ was first identified during the floricane-fruiting cycle on 31-May, 2017 in a substrate block where seedling populations had been planted into 10 L pots the prior spring. The selection ultimately identified as ‘HFG 1714’ was first propagated asexually by crown division (of that original potted ‘HFG 1714’ plant, which became the mother-plant for subsequent ‘HFG 1714’ plants) in December 2017 in Watsonville, California, Santa Cruz County, USA.

The crown on the original ‘HFG 1714’ plant was parted into basal cane pieces (approximately 15 cm long) with root attached, re-potted and placed inside of a screenhouse. The remaining roots were chilled for 4 weeks and planted inside into an onsite greenhouse to force etiolated shoots. Once rooted, individual etiolated shoots (propagules) were planted into a single 10-plant plot. Harvest and post-harvest data were collected from plots of ‘HFG 1714’ for two years, from 2018 through 2019.

In June 2019, actively growing shoots from the original mother-plant were harvested from inside the screenhouse and sent to Lafayette, OR, USA, where vegetative material was established in vitro for micropropagation. Tissue-cultured plantlets of ‘HFG 1714’ were tested in replicated blocks across diverse environments within North America for performance and genetic stability.

BRIEF SUMMARY OF THE INVENTION

The present cultivar, ‘HFG 1714’ offers several advantages over the existing cultivar and maternal parent, ‘PBBrasp1348’ (U.S. Plant Pat. No. 29,368P2). Particularly for fruit firmness, ‘HFG 1714’ is noteworthy for its extreme firmness and extended post-harvest shelf life, as compared to the softer fruit and shorter post-harvest shelf life of ‘PBBrasp1348’. Unlike its maternal parent, ‘HFG 1714’ is mid-season, whereas ‘PBBrasp1348’ fruits earlier in the season. Like its parent ‘PBBrasp1348’, fruit color of ‘HFG 1714’ is non-darkening under post-harvest evaluations, maintaining a fresh appearance. ‘HFG 1714’ offers greater yields over ‘PBBrasp1348’. The extreme firmness, long shelf life, and improved yields of ‘HFG 1714’ offer significant advantages to growers, who require high yielding cultivars that can maintain a fresh appearance many days post-harvest.

In contrast to the male parent 1338’ (unpatented), ‘HFG 1714’ is significantly greater in average berry weight and yield. ‘HFG 1714’ maintains the reduced acidity and aromatics of its male parent ‘1338’, yet offers a standard pink/red color common in fresh-market commodity raspberry than the less familiar yellow-peach colors of ‘1338’. ‘HFG 1714’ maintains the sensorial properties of male parent ‘1338’ while improving the yield and average berry weight; these traits offer growers the ability to produce a large crop of berries of pink/red color, with a flavor that is highly desirable to consumers.

In contrast to the comparison cultivar ‘PBBrasp1381’ (U.S. Plant Pat. No. 29,369) ‘HFG 1714’ has a non-darkening pinkish-red color after 7 days in cold storage (2° C.), whereas ‘PBBrasp1381’ darkens significantly to a medium red color. ‘HFG 1714’ possesses a similar berry weight, firmness and extended shelf life associated with ‘PBBrasp1381’. ‘HFG 1714’ has reduced acidity and increased sugar content in comparison to ‘PBBrasp1381’. These characteristics offer an improved flavor in comparison to the comparison cultivar.

Thus, these characteristics help define ‘HFG 1714’ as a new and distinct cultivar of primocane-fruiting raspberry. ‘HFG 1714’ may be recognized by its large non-darkening, pinkish-red berries, high yield, reduced acidity, aromatic flavor, extreme firmness, and shelf life.
