primocane

It’s the first primocane blackberry, producing huge, round berries on first-year wood.

In raspberries, these types are called primocane fruiting, fall fruiting, or everbearing. '

Pomona Fruits – introducing the first primocane blackberry Reuben, cropping on first year’s growth.

They are also responsible for developing the primocane fruiting blackberries such as 'Prime-Jan' and 'Prime-Jim'.

The fungus overwinters in old primocane leaf debris trapped in bundles of canes where they are tied to the trellis wire.

Horticultural Research International at East Malling in England has just released 'Autumn Byrd', an extremely early fall (primocane) fruiting variety.

Royalty is the dominant purple raspberry and primocane fruiting varieties include Autumn Britten, Autumn Bliss and Heritage.

Competition for the available assimilates between the 1st-year cane, the primocane, and the 2nd-year cane, the floricane, is minimized by the temporal and spatial separation of their activities.

Prime-Jim' and 'Prime-Jan' were released in 2004 by the University of Arkansas and are the first cultivars of primocane fruiting blackberry.

Recently the University of Arkansas has developed primocane fruiting blackberries that grow and flower on first-year growth much as the primocane-fruiting (also called fall bearing or everbearing) red raspberries do.

In its first year, a new stem ("primocane") grows vigorously to its full height of 1-3 m, unbranched, and bearing large pinnate leaves with three or five leaflets; normally it does not produce any flowers the first year.

Until a few years ago, it was almost impossible to produce winter blackberries commercially in California, even under protective hoop houses, but the advent of new varieties, called "primocane," is revolutionizing the blackberry industry, just as happened previously with raspberries.

Fall (primocane) fruiting varieties should be cut to the ground in winter; when new growth commences, early fruiting can be promoted in these varieties by pinching out the growing tip when the canes reach about 1 m.

Other desired characteristics sought are early floricane fruiting, late floricane fruiting, compact growth, early primocane fruiting, and desirable fruit traits, such as bright, non-darkening red colour and fruit that release easily from the receptacle.
