In the past, many seed companies would produce seed for tomato varieties, and this usually resulted in a price war, with farmers buying the cheapest seed.
Modern hybrids have been hand-pollinated and each company has sole ownership of the varieties developed. It is therefore in its interest to ensure that the seed is disease-free and of good quality, rather than taking shortcuts to produce cheaper seeds in order to generate sales.
