USPP35020P2 - Shallot plant named ‘Innovator’ - Google Patents

Abstract

A new and distinct variety of shallot plant with high resistance to Peronospora destructor and long storability.

Description

Botanical classification: Allium cepa.

Varietal denomination: ‘Innovator’.

BACKGROUND OF THE INVENTION

The present invention comprises a new and distinct shallot plant known by the varietal name ‘Innovator’. The new variety is the result of a planned breeding program conducted in The Netherlands and was discovered in December of 2018. The purpose of the breeding program was to provide shallot varieties with harvest reliability, shape uniformity, and long storage life. ‘Innovator’ is the result of the crossing of an Allium cepa variety referred to by the applicant as 1010 (female parent, unpatented) with an Allium cepa variety referred to by the applicant as 1017 (male parent, unpatented). The claimed variety named ‘Innovator’ is one variety from the stated cross that was selected over its siblings for plant patent protection. The first act of asexual reproduction of ‘Innovator’ was conducted in April of 2021 by splitting and replanting its bulbs in soil in Broek op Langedijk, The Netherlands. ‘Innovator’ has been trial and field tested and has been found to retain its distinctive characteristics and remain true to type through successive asexual propagations. The present invention has not been evaluated under all possible environmental conditions. The phenotype may vary with variations in environment without a change in the genotype of the plant.

‘Innovator’ is similar to both of its parental varieties in time of harvest maturity and internal coloration. However, ‘Innovator’ exhibits a different shape and dry skin color than both of its parental varieties. Further, its female parent is distinguishable from ‘Innovator’ in being susceptible to mildew and shorter in overall plant length. Additionally, its male parent exhibits a longer overall plant length and darker overall coloration than ‘Innovator’.

When compared to shallot variety named ‘Conservor’ (unpatented), ‘Innovator’ is similar to ‘Conservor’ in storage suitability. However, ‘Innovator’ exhibits a different dry skin color than ‘Conservor’ (RHS 176C for ‘Innovator’ and RHS 177C for ‘Conservor’), a larger bulb size than ‘Conservor’, and a more elongated bulb shape than ‘Conservor’). Further, contrary to ‘Conservor’, ‘Innovator’ is highly resistant to Peronospora destructor.

When compared to other shallot varieties known to the applicant, ‘Innovator’ can be distinguished based on its high resistance to Peronospora destructor, bulb size, shape, and dry skin color.

DESCRIPTION OF THE DRAWINGS

The accompanying photographic drawings illustrate the new variety, with the color being as nearly true as is possible with color illustrations of this type:

FIG. 1 shows a field of plants of the new variety (3 months after planting);

FIG. 2 shows multiple, dried bulbs of the new variety (3 months after harvest);

FIG. 3 shows multiple spears of the new variety (harvested 8 months after planting); and

FIG. 4 shows a close-up view of freshly picked spears of the new variety (harvested 8 months after planting).

DESCRIPTION OF THE PLANT

The following detailed description sets forth the characteristics of the new variety. Plants of the new variety were soil grown in the Netherlands under open field conditions under natural light. Growth conditions for ‘Innovator’ were maritime climatic conditions in a long-day region with more than 15 hours of daylight during the longest day. The new variety grows well in drained soil with a pH of about 5-7. Drilling or planting of bulbs can occur as early as the beginning of March, with harvest of bulbs at the end of August for Northern European conditions. Development of first leaves following planting/drilling is approximately 2-3 weeks. A planted bulb will mature in its first year and flower in its second year. The color readings and measurements were taken outdoors in the Netherlands under natural light on approximately 3 month old plants in the field and indoors under LED lights on 8 month old harvested plants.
