组织培养在农业克隆繁殖中的重要性每年都在不断增加。一般来说，组织培养繁殖的商业用途限于具有高单位价值的作物，如植物和果树和坚果树。低成本、高产量的繁殖系统是不可用的，但对中等单位价值的作物如莴苣、芹菜和许多其他作物可能具有重要价值（表1）。对于这些作物，体细胞胚胎发生的高容量繁殖潜力与低成本交付的合成种子的形成相结合，将为克隆繁殖开辟一个新的领域。用于合成种子生产的候选作物可以分为两类：1）具有强大技术基础的作物，使得目前可以生产高质量的体细胞胚，以及2）具有强大商业基础的作物。后一类作物的种子成本很高，因为生育问题，配子不稳定，劳动密集型杂交种子的形成，或其他一些原因。目前，很少有作物（表1）满足这两个要求，并适合合成种子技术。
The importance of tissue culture for clonal propagation in agriculture continues to increase each year. In general, commercial use of tissue culture propagation has been limited to crops that have a high per-unit value, such as ornamentals and fruit and nut trees. A lowcost, high-volume propagation system is not available, but could be of significant value to medium per-unit value crops such as lettuce, celery, and many others (Table 1). For these crops, highvolume propagation potential of somatic embryogenesis combined with formation of synthetic seeds for low-cost delivery would open a new field for clonal propagation. Candidate crops for synthetic seed production can be classified into two categories: 1) those that have a strong technological basis, such that high quality somatic embryos can currently be produced, and 2) those with a strong commercial basis. The latter category of crops are those in which seed costs are high because of fertility problems, gamete instability, labor-intensive hybrid seed formation, or a number of other reasons. Currently, there are few crops (Table 1) that meet both requirements and are suitable for synthetic seed technology.
