Lemonax is a tomato hybrid intended for cultivation in open ground and under plastic coverings. The plant has an indeterminate or semi-determinate growth habit, reaching a height of about 1.2-1.3 meters and requires pinching to form a high-quality yield. Leaves are green and arranged horizontally, while inflorescences are intermediate type. The hybrid is early-maturing, ripening on average in 94-98 days, allowing for a quick harvest. Lemonax fruits have round or flat-round shape with yellow ripe skin color. The average fruit weight is about 21.4 grams, although some specimens can reach up to 250 grams and more. Tomatoes are meaty with high flavor quality, making them ideal for fresh consumption, as well as for salads and fresh juices. The taste evaluation of the fruits reaches 5 points, confirming their excellent organoleptic properties. The Lemonax hybrid exhibits high resistance to major tomato diseases, including tomato mosaic virus (ToMV), verticillium wilt, alternaria, and root fusarium rot. This ensures stable yield and high fruiting capacity. The yield of this variety reaches approximately 2.97 kg per square meter, making it attractive for gardeners and farmers seeking quality and healthy produce.
