Abstract

A new variety of Gentiana L. plant (Japanese gentian) which has a narrow lanceolate leaf shape and a stem length of 71.0 cm on average.

Description

Common name: Japanese gentian.
Botanical classification: Gentiana L. hybrid.
Variety denomination: ‘Ashiro 29-2065’.
BACKGROUND OF THE NEW VARIETY
The present invention relates to a new and distinct variety of Japanese gentian, Gentiana L., which has been given the variety denomination ‘Ashiro 29-2065’.
This new gentian has a narrow lanceolate leaf shape and a stem length of 71.0 cm on average. It is adapted for use as cut flowers or pot flowers.
ORIGIN OF THE VARIETY
The variety resulted from a multiple-step cross-breeding program starting from a group of unpatented varieties. The ancestor varieties were unpatented strains owned by the applicant, having the company-internal names: ‘17INP’ which belongs to the species Gentiana triflora, and ‘25-322-R1’, ‘26-904’, ‘12-320-1’, ‘14-526-2’, ‘11-24-1’, ‘11-192-1’, ‘13SH’, ‘10-76’, ‘6-62’, ‘12-186-1’, ‘12-212-1’, ‘25-817’, ‘17SUP’, and ‘8-130SP6A1’, which belong to the species Gentiana scabra. Group crosses and/or self-crosses with a single individual were performed. The program had seven steps, as shown in the map of FIG. 6 , which also indicates the company-internal names of the intermediary, unpatented strains. At each step, the individuals with good plant and flower shape were selected. The corresponding species identification is (((scabrax(scabraxtriflora))xscabra)))x((scabraxtriflora)xscabra)).
With respect to the direct parents ‘28-2012Co-3b’ and ‘27-836-53’, the instant variety ‘Ashiro 29-2065’ has a triploid and double-flowered flower type, whereas ‘28-2012Co-3b’ has tetraploid and double-flowered flower type, and ‘27-836-53’ has diploid and single-flowered flower type.
The multiple-step cross-breeding program was performed over multiple growing seasons up to 2018; in October 2018, selection of the variety was performed. We asexually reproduced the variety by vegetative reproduction through cuttings, tissue culturing via lateral bud culture, and in October 2020, the new variety was found to be stable and asexually reproduced true to type in successive generations.
The variety was developed and propagated in Iwate, Japan.
The variety can be propagated by cutting (optimal timing is mid-February) and/or tissue culturing via lateral bud culture.
Cultivation of the variety does not require particular conditions. Maintenance and storage method of the plant material can be by tissue culture via lateral bud culture.
The variety is adapted for use as cut flowers or pot flowers.
SUMMARY OF THE VARIETY
The variety is distinguished by its lanceolate leaf shape and by its stem length of 71.0 cm on average, as compared to ‘Lovely Ashiro’ variety whose leaf shape is broad lanceolate and whose stem length is 110.1 cm on average. ‘Lovely Ashiro’ is unpatented.
A comparison with Lovely Ashiro variety is presented as follows in Table 1:
TABLE 1
‘Lovely Ashiro’ ‘Ashiro 29-2065’
Leaf shape Broad lanceolate narrow lanceolate
Stem length 110.1 cm 71.0 cm
Additional distinguishing characteristics of the ‘Ashiro 29-2065’ plant are the five-six (5.4 on average) lobes of the corolla, and the light reddish purple color (N75A on The RHS Colour Chart), with spots, of the secondary lobes with acute apex in-between the main lobes of the corolla.
