Mexico is the center of origin and diversification of the husk tomato, but its production depends on native germplasm and local varieties. This contribution aimed to describe the INI-181 variety and its agronomic behavior. The variety was generated by stratified mass selection and individual selection methods. Varietal characterization was carried out in homologous cycles in spring-summer of 2017 and 2018, at the Bajío Experimental Field, Celaya, Guanajuato, Mexico, based on the descriptors of the International Union for the Protection of New Varieties of Plants. Agronomic behavior was evaluated under a completely randomized experimental design with four replications. Morphological and phenological traits were recorded and analyzed with the Kruskal-Wallis test (p≤ 0.05). Plants of the INI-181 variety are semi-erect with long internodes without pigmentation. Stem without pubescence. Green elliptical leaves of medium length with semi-dentate margin. Medium-sized flower. Green and firm fruit, strongly attached to the calyx, with shallow peduncular cavity, round apex and green pulp with 3.81 mg GAE 100 g-1 tomatidine on average. Intermediate flowering. Medium-sized yellow seed. It is tolerant to powdery mildew (Oidium sp.) and the stem borer (Melanagromyza tomaterae Steyskal). In 10 kg of fruit, 90 to 130 g of seed is obtained on average.
