Description

CROSS-REFERENCE TO RELATED APPLICATION This application claims priority to U.S. Provisional Application No. 63/477,688 filed on Dec. 29, 2022, which is hereby incorporated by reference in its entirety. FIELD OF DISCLOSURE The disclosure relates to the field of plant breeding and, more specifically, to the development of lettuce variety NUN 09181 LTL. The disclosure further relates to vegetative reproductions of lettuce variety NUN 09181 LTL, methods for tissue culture of lettuce variety NUN 09181 LTL, and to phenotypic variants of lettuce variety NUN 09181 LTL. The disclosure also relates to progeny of lettuce variety NUN 09181 LTL, and the hybrid varieties obtained by crossing lettuce variety NUN 09181 LTL as a parent line with plants of other varieties or parent lines. BACKGROUND OF THE DISCLOSURE The goal of vegetable breeding is to combine various desirable traits in a single variety. Such desirable traits may include greater yield, resistance to diseases, insects or other pests, tolerance to heat and drought, better agronomic quality, higher nutritional value, enhanced growth rate, and improved shelf life. The development of commercial lettuce cultivars or varieties requires the crossing of lettuce plants, and the evaluation of the crosses. Pedigree breeding and recurrent selection are examples of breeding methods used to develop cultivars from breeding populations. Breeding programs combine desirable traits from two or more varieties or various broad-based sources into breeding pools from which cultivars are developed by selfing and selection of desired phenotypes. The new cultivars are crossed with other varieties and the inbred lines or hybrids from these crosses are evaluated to determine which have commercial potential. All cultivated forms of lettuce belong to the highly polymorphic species Lactuca sativa that is grown for its edible head and leaves. Lactuca sativa is in the Asteraceae (Compositae) family. Lettuce is related to chicory, sunflower, aster, dandelion, artichoke, and chrysanthemum. L. sativa is one of about 300 species in the genus Lactuca. There are many types of lettuce, and new types are constantly in development. Types of lettuce include Cutting/Leaf, Iceberg/Crisphead, Cos or Romaine, Batavian, Salinas Group, Latin, Butterhead, Great Lakes Group, Eastern (Ithaca) Group, Bibb, Vanguard Group, Multileaf, or Stem lettuce. Lettuce is typically consumed fresh, occasionally as a cooked vegetable, or a healthy garnish. It is popularly used in salads, wraps, and sandwiches. Fresh lettuce is available in the United States year-round although the greatest supply is from May through October. For planting purposes, the lettuce season is typically divided into three categories, early, mid and late, with the coastal areas planting from January to August, and the desert regions planting from August to December. California and Arizona are the two largest producers of lettuce in the United States. Changes in lifestyle primarily due to increasing health awareness results to growing demand for healthy convenience food. Supermarkets, restaurants, catering firms, and convenience stores are constantly looking for healthy and visually appetizing garnishing for sandwiches, wraps, and ready-to-eat snacks such as salads. The changing food and consumer trends present opportunities for breeding companies to develop new varieties with specific shapes and size of leaves, prominent color, glossiness, taste, crispiness, and a wide variety of texture. Other breeding objectives include disease or pest resistance, yield, prolonged shelf life, and suitability to climatic requirements. SUMMARY OF VARIOUS ASPECTS OF THE DISCLOSURE The disclosure provides for a lettuce variety NUN 09181 LTL, products thereof, and methods of using the same. NUN 09181 LTL is a multileaf green (high tech) lettuce variety and is suitable for growing in a greenhouse. In another aspect, the plant of lettuce variety NUN 09181 LTL, or part thereof, or progeny thereof comprises resistance to Downy Mildew (Bremia lactucae) Isolates B1:16-39EU and Lettuce Mosaic Virus (LMV), measured according to UPOV standards described in TG/13/11. The disclosure also provides a lettuce plant or a part thereof having all of the physiological and morphological characteristics of the plant of lettuce variety NUN 09181 LTL when grown under the same environmental conditions. The disclosure also provides for a progeny of lettuce variety NUN 09181 LTL. In one aspect, the disclosure provides a progeny retaining all or all but one, two, or three of the “distinguishing characteristics” of the plant of lettuce variety NUN 09181 LTL, or all but one, two, or three of the “morphological and physiological characteristics” of the plant of lettuce variety NUN 09181 LTL and methods of producing that plant or progeny. In another aspect, the disclosure provides a plant or a progeny having all of the physiological and morphological characteristics of the plant lettuce variety NU
