For example, in the Sudan savannah in West Africa, whether farmers can afford hybrid seeds depends on who is in charge of the family. This sounds outrageous, but this is the reality. So, no matter how advanced the breeding technology is, it must take into account the actual conditions of the local area. 6.2 Sustainability concerns and environmental impact When it comes to sorghum hybrid breeding, people are increasingly concerned about sustainability. The "stay-green" trait is interesting and can help crops resist drought and lodging, but the effect depends on the location-some areas have obvious yield increases, but they may not work in other places (Jordan et al., 2012). The photoperiod-sensitive hybrids developed in Mali are a successful case. They use Guinea germplasm and perform particularly well under farmers' actual planting conditions (Rattunde et al., 2013). But then again, the most surprising thing about this hybrid is not only that the yield has increased, but more importantly, it is both environmentally friendly and allows farmers to earn more money, which is a win-win situation. Of course, breeding can never be a one-size-fits-all thing. The key is to adapt to local conditions. 6.3 Regulatory and ethical considerations When it comes to hybrid breeding, it is not enough to just consider the technology. The regulatory and ethical issues are even more troublesome. Take genetically modified crops for example. The review standards of each country are different. If you are not careful, you may get stuck in the approval process. There is a successful case in West Africa. After using improved hybrid seeds, not only the yield has increased, but also the people's dining tables have become richer (Smale et al., 2018). However, this matter also has two sides-experts have to walk a tightrope between increasing yields and protecting local varieties (Suguna et al., 2021). The most troublesome thing is that when promoting new varieties, you have to consider fairness, so that only large farmers can afford it, and small farmers can only stare blankly. So, breeding not only requires understanding agriculture, but also balancing the interests of all parties. 7 Future Directions in Hybrid Breeding 7.1 Emerging technologies in hybrid breeding When it comes to the future of sorghum breeding, those wild, undomesticated germplasm resources may come in handy. Although these "wild" varieties may not look impressive, they contain many good genes (Jordan et al., 2011). Recently, it has been found that after the excellent alleles of these wild species were introduced into cultivated varieties, the genetic variation of grain yield was actually maintained quite well. However, the most exciting thing is the breakthrough in marker-assisted breeding technology-now DNA markers can quickly lock in disease-resistant and high-yield gene loci (Baloch et al., 2023). Think about it, breeding used to be like looking for a needle in a haystack, but now with these new technologies, the efficiency has increased by many times. Of course, the specific effect depends on the field performance, but at least it gives breeding experts new hope. 7.2 Potential for precision breeding and ai applications In recent years, breeding technology has become increasingly "smarter". Take genome editing, for example. Now it is much more accurate to breed new disease-resistant and drought-resistant sorghum varieties than before (Lassoued et al., 2018). Especially with climate change becoming more and more severe, these technologies come at the right time. But the most surprising thing is that even artificial intelligence has come to help with breeding-it can quickly analyze massive amounts of data and predict which hybrid combinations are the most reliable. Although it sounds a bit sci-fi, it does make breeding work a lot easier. Of course, these high-tech technologies are not omnipotent, and field trials are still necessary, but at least they allow breeders to avoid many detours. In my opinion, traditional experience combined with these new tools may really produce some amazing new varieties. 7.3 Policy and investment needs To develop these new breeding technologies, scientific breakthroughs alone are not enough. Without adequate policy support and insufficient funding, even the best technology can only stay in the laboratory. There is an example in West Africa where hybrids made from Guinea germplasm are indeed much more productive than local varieties (Kante et al., 2019), but promotion is still difficult. In the final analysis, the regulatory framework must be straightened out first so that farmers can use them with confidence. And there are small farmers who need
