Hop plant named ‘NZH063’

Abstract

A new and distinct hop plant is described. The new cultivar results out of selection from a population of seedlings derived from deliberate crossing ‘Cascade’ (seed parent; not patented) and tetraploid male selection 00.L123-168 (not patented). The new cultivar, ‘NZH063’, is characterised by having cones which are late-season maturing and having medium alpha acid content. The new cultivar is suitable for beer flavouring.

BOTANICAL DESCRIPTION

(6) The following is a description of the new cultivar with colour terminology in accordance with The Royal Horticultural Society Colour Charts (R.H.S.C.C.) 2001 edition. The specimens described were six years old and were grown at Motueka, New Zealand. The observations were made over the 2019-2021 seasons. Plant form and vigour: Mature plants had a normal growth type and produced a yield (averaging 2.28 tonnes/ha) of late-season maturing cones. The shape of the plant tended to be cylindrical to club shaped with the head being high to very high volume. The main shoot of a one year old plant had an average vine diameter half way up the vine of 8.7 mm, and anthocyanin coloration was weak. Node pubescence was weak. The average internode length was 246 mm. Laterals: The attitude of the laterals was spreading. The side shoots from the middle third of the plant were medium in length, averaged 51.8 cm, and produced a medium number of cones, an average of 5.6 per node. The side shoots from the top third of the plant were longer with an average length of 54.8 cm and produced an average of 2.8 cones/node. There was an average of 6.9 nodes per lateral in the middle third of the plant and an average of 6.3 nodes per lateral in the upper third of the plant. Stipule pose is upright and stipule colour is green 144C. Leaves: The leaves were lobed with predominantly five lobes. The medium sized, medium blistered leaves were opposite with crenate margins. The average leaf length was 151 mm and average width was 166 mm. The upper leaf surface colour was Green, 137A with medium intensity. Venation type is palmate and venation colour is 144A. Petioles have an average length of 85 mm, an average width of 4 mm and the colour is near 60B. Foliage density: The density of the foliage of the side shoot from the middle third of the plant for NZH063 was medium. Cones: Were medium in size and medium-ovate in shape in longitudinal section; in cross section they were square in shape. The cone average length was 46.7 mm and average width 21.9 mm. Bracts were medium-large in size, with an average length of 21.1 mm and average width 13.6 mm, Green in colour, near 145C. The cones were open and the bract apex was short in length. Bracteole had an average length of 16.2 mm and average width of 10 mm. The bracterole colour was 157B. Strigs were long, and had an average length of 34.7 mm, with an average width of 3.7 mm. The colour of the strig was Green, near 145B. Physiological timing: Flowering commences mid-season in Motueka, New Zealand around the 5-15 January. Harvest is late in the New Zealand season, commencing mid- to late-March, under normal conditions. Chemistry profile: ‘NZH063’ has undergone extensive chemistry profile testing. NZH063 has medium alpha acid levels around 9%, low Beta acid levels around 4% and cohumulone levels around 32%. Use: Primarily flavouring and bittering ingredient for beer. Pest and disease: ‘NZH063’ does not appear particularly resistant or susceptible to any particular pests or diseases known to afflict Humulus lupulus. Hardiness: The plant cold hardiness according to the American zone classification has not been determined.
