Fenugreek has been cultivated worldwide for millennia and is employed in various capacities such as food flavoring, essential oil applications, and traditional medicines. Continuous exploration of additional uses and applications for fenugreek by-products is underway. Further research is essential to maximize yield per hectare, optimize preservation, and develop more suitable oil extraction methods, particularly in the developing world where traditional methods prevail in fenugreek leaf and flower harvesting, as well as postharvest processing. Despite there have been reports of over 100 different Trigonella species, Trigonella foenum-graecum L. is the species that is most widely farmed. Genetic diversity, intra- and interspecific variability, and genetic interactions between species are poorly understood. Research on the genetic relationships between the various Trigonella species is necessary to investigate further potential genetic improvements for the crop, especially its nutraceutical qualities, which the pharmaceutical industry is interested in. These include steroidal sapogenins, trigonelline, galactomannan, and isoleucine content. Owing to little success in hybridization, the genes from related species have not been exploited in fenugreek, but here the double haploid breeding can offer better scope for improvement in productivity and medicinal quality.
