References [1]. Guidelines for maintaining purity of pepper varieties. 1984. Isolation distance for tomatoes. [1].Tomato can be a good natural source of lycopene. Obviously, these resources and geography are difficult to achieve. If space is tight, varieties may be separated by only 10 feet. The minimum isolation distance between different cultivars of tomatoes for seed production is relatively short. 3 Isolation distance for certified seed production shall be at least 500 feet (152.07m) from varieties of dissimilar adaptation. 5 This distance applies when fields are 5 acres (2ha) or larger in area. Isolation distance: Isolation distance is the minimum separation required between two or more varieties of the same species for the purpose of keeping seed pure. Also, tomato volunteers from previous seasons could remain undetected within the isolation perimeter. Keep in mind that an understanding of microenvironment and pollinator pressure is very important in making The following is a list of USDA recommended distances between different plant and variety types to ensure seed purity. See “Isolation Distance Requirements for Tomatoes” for more detailed information on planting distances. Most countries specify a distance of between 30 and 200 m, the main consideration being that the distance should be sufficient to avoid admixture at harvesting time. Hence, lycopene can be extracted using different extraction and isolation methods. This is because of the crop's high level of self-pollination. Notes on Seed Storage. Isolation Distance Requirements for Peppers Isolation Distance Requirements for Tomatoes. Tomato, wild type (L. pimpinellifolium) ... isolation distance can be used to decrease the distance by perhaps no more than 10%: this figure is a guideline, not a rule.

To obtain 100% seed purity by isolation distance, very large separations are required, possibly a 1/4 mile or more. Of course, more simple, new, and environment friendly sorbent such as nano and bio materials can be used in the isolation and purification of lycopene from tomato paste [2]. Species in the same genus or family often have similar minimum isolation distance requirements, but occasionally certain varieties within a species may require larger isolation distances.
