Hybrid plants are a crossing between two selected parent plants achieved via controlled pollination (see how are plants propagated). The seeds produced by this process are called F1 or F1 Hybrids. These hybrids will exhibit very specific qualities. Hybrids have quickly come to dominate the seed market. However, in spite of their increased market presence of hybrids, there are several factors to be considered. They can be summarized as follows:
Loss of Genetic Diversity
The massive shift to the use of hybrids has resulted in a severe reduction in seed varieties. Between 1984 and 1987, 54 of the 230 American and Canadian mail-order seed companies went out of business. With their closure, 943 non-hybrid varieties, or approximately 19% of all varieties, were lost. This trend continues based on the evolving demands of the agriculture industry, i.e. extreme consolidation and the globalization of supply chains. However, genetic diversity must be maintained as it is essential to the survival and adaptability of any given species (see crop wild relatives), something that will be increasingly relevant as a result of changes in climate and pest adaptations.
Hybrid seeds are typically more expensive due to the financial investment required by the seed companies in order to develop new strains. Investment in this respect relates to finding two suitable partner plants and hand-pollination. The higher cost is passed on to growers. Growers who are producing for the market must then pass on the costs to consumers.
Seeds from hybrids cannot be saved as the offspring will be genetically unpredictable. As a result, growers are forced to purchase new seeds each year. This puts undue financial stress on small-scale growers, which further contributes to the consolidation of the agricultural system. Further consolidation means more extreme shifts to mechanization which requires the use of chemicals that typically harm the environment and erode the relationship between food producer and consumer.
Private Property Rights
Unlike open-pollinated seeds, hybrid seeds are patented. This means that the genetic rights to the plants belong to the company producing the seeds rather than being a public good. With seed companies becoming increasingly consolidated, the power and control continue to become concentrated. In 2007, three companies – Monsanto, Dupont and Syngenta – controlled 47% of the world’s seed market with Monsanto alone controlling one-quarter of the market. Since that time, Monsanto has merged with Bayer, Dupont merged with Dow, and Syngenta merged with ChemChina. These mergers resulted in the development of an extremely powerful oligarchy that has a stronghold on the world’s seed market. This chokehold means diminished autonomy and a world subjected to subversive tactics designed to broaden the companies’ influence in the world’s economy.
The hybrid varieties produced are typically designed for commercial growers. Therefore, the primary focus of plant breeders is tolerance for machine harvesting and processing, with flavor and texture being of minimal importance. Likewise, hybrid varieties are designed to ripen uniformly which is not necessarily of benefit to home or smaller producers who seek to extend the growing season over as long of a period as possible.
