USPP37154P3 - Hop plant named ‘NZH-2077’ - Google Patents

Abstract

The new hop plant ‘NZH-2077’ is provided. The new plant was produced by crossing ‘05.L205-239’ (the female parent, i.e., the seed parent; not patented) with a diploid male selection ‘L13.008-004’ (i.e., the pollen parent; not patented) in the course of a planned breeding program. ‘NZH-2077’ is characterized by having large, medium compact cones which are late season maturing.

Description

CROSS REFERENCE TO RELATED APPLICATIONS

This application claims priority to U.S. Provisional Patent Application No. 63/642,029, which was filed on May 3, 2024, the contents of which are hereby incorporated by reference for all purposes.

Latin name of genus and species of plant claimed: Humulus lupulus L.

Variety denomination: ‘NZH-2077’.

BACKGROUND OF THE INVENTION

The new variety of hop, Humulus lupulus L., of the present invention was created in the course of a planned breeding program carried out at Motueka, New Zealand. It was selected from a population of triploid seedlings derived from crossing the diploid ‘05.L205-239’ (the female parent, i.e., the seed parent; not patented) with a tetraploid male selection ‘L13.008-004’ (i.e., the pollen parent; not patented).

The parentage of the new variety can be summarized as follows:
‘05.L205-239’ x ‘L13.008-004’

The cross was carried out in January 2015. The seeds resulting from the above cross were germinated and the seedlings were then raised and planted in a field at Motueka, New Zealand in November 2015. The seedlings remained in the field for the 2015-2016 and 2016-2017 seasons to allow for agronomic, sensory, and chemistry traits to be measured and/or assessed. Selective study resulted in the identification of a single plant of the new variety from the population of seedlings derived from the above cross.

During the 2019 season the new variety was clonally propagated using soft tip methods and 15 rooted cutting plants were potted. The resulting plants were found to be true to type demonstrating that the characteristics of the new variety are stable and strictly transmitted by asexual propagation from one generation to another.

Further plants of the new variety were asexually propagated and a trial plot was planted in 2021-2022.

SUMMARY OF THE INVENTION

It was found that the new variety of hop plant of the present invention is characterized by having large cones that are medium in compactness which are late season maturing.

The new variety can be readily distinguished from its ancestors. More specifically, the new variety is triploid whereas the seed parent, ‘05.L205-239’, is a diploid and the pollen parent, ‘L13.008-004’, is a tetraploid. Moreover, the new variety of the present invention can readily be distinguished from other similar non- parental varieties. For example, when compared to ‘Southern Cross’ (not patented), the new variety has cones which mature late in the season, compared to ‘Southern Cross’ which has mid-season maturing cones. In addition, ‘85-03-06’ (not patented) has small cones compared to the large cones of the new variety.

The new variety has been named ‘NZH-2077’. The new variety was previously named L15.052-077. L15.052-077 has also been referred to as the Breeder Code for the new variety.

DETAILED BOTANICAL DESCRIPTION

The chart used in the identification of colors is that of The Royal Horticultural Society (The R.H.S. Colour Chart, 2001 edition). The terminology which precedes reference to the chart has been added to indicate the corresponding color in more common terms and The R.H.S. Colour Chart designation herein represents the closest color observed on the majority of the specified botanic features. The description is based on two to three-year-old specimens of the new variety, observed during the 2024-2025 season while growing in Motueka, New Zealand.
