Variety Identification Variety identification is the process of identifying a tomato based on its distinctive characteristics.
Varietal isolation Varietal isolation involves separating different tomato varieties from one another to maintain the varietal purity of the seeds.

Variety labelling Variety labelling involves permanently labeling plants and fruits with tags, numbers, or codes.
Vegetative-Generative Balance · vegetative-generative balance Vegetative-generative balance refers to the proper proportion between the growth of foliage and fruit set.
Vegetative Propagation · asexual reproduction, propagation from cuttings Vegetative propagation involves producing new plants from parts of the parent plant, most commonly from lateral shoots.
Vascular tissue Vascular tissues are responsible for transporting water, nutrients, and assimilates between the roots, leaves, and fruits.
Variety stabilisation · varietal stabilization Variety stabilization is a multigenerational process aimed at increasing a variety’s uniformity and genetic stability.
Verticillium Wilt · Verticillium wilt of the tomato Verticillium wilt is a fungal disease of the tomato vascular system caused primarily by Verticillium dahliae.
Vascular Wilting · vascular wilt Vascular wilt is a symptom of diseases that damage the vascular tissues, such as fusarium wilt or verticillium wilt.
Ventilation · tunnel ventilation, greenhouse ventilation Ventilating a tunnel or greenhouse involves exchanging air with the outside environment.
