Integrating genomic selection (GS) and emerging technologies, such as high-throughput genotyping, phenotyping, and gene editing, can accelerate the development of cultivars with improved yields and enhanced resistance to biotic and abiotic stresses (He and Li, 2020). Furthermore, increased sharing of genetic resources, genomic data, and bioinformatics expertise between developed and developing economies can help meet the challenges posed by climate change and the growing demand for food. Such collaborations can also facilitate the exchange of best practices and innovative breeding techniques, ultimately contributing to the global effort to enhance crop resilience and productivity. By addressing these challenges and leveraging the opportunities, the utilization of genetic resources for sweet potato breeding in China can be significantly improved, leading to more resilient and productive crop varieties (Cooper and Messina, 2022). 7 Future Directions for Sweet Potato Breeding in China 7.1 Expanding the genetic base for breeding To enhance the genetic diversity of sweet potato breeding programs in China, it is crucial to incorporate a wide range of genetic resources. This includes local landraces, wild relatives, and elite lines from international breeding programs. By broadening the genetic base, breeders can introduce new traits that improve yield, disease resistance, and nutritional quality. For instance, studies on potatoes have shown that incorporating diverse genotypes can lead to the discovery of unique alleles that are beneficial for breeding (Wang et al., 2019). Similar strategies can be applied to sweet potatoes to ensure a robust and resilient breeding program. 7.2 Leveraging advances in genomics and biotechnology The integration of modern genomics and biotechnological tools can significantly accelerate sweet potato breeding efforts. Techniques such as CRISPR/Cas9 and TALENs have been successfully used in other crops like potato to enhance nutritional content and remove anti-nutritional compounds (Hameed et al., 2018). These technologies can be employed to develop transgene-free sweet potato varieties with improved traits. Additionally, the availability of sweet potato genome sequences can facilitate marker-assisted selection and genomic selection, making the breeding process more precise and efficient. 7.3 Strengthening breeding-research partnerships Collaborative efforts between breeding programs and research institutions are essential for the continuous improvement of sweet potato varieties. Partnerships with international organizations like the International Potato Center (CIP) can provide access to advanced breeding techniques and genetic resources (Ojwang' et al., 2023). Moreover, multidisciplinary workshops and the use of tools like the G+ tools can help evaluate and enhance the gender-responsiveness of breeding programs, ensuring that the developed varieties meet the needs of all stakeholders (Swanckaert et al., 2021). 7.4 Addressing consumer preferences and market needs Future sweet potato breeding programs in China should be increasingly demand-driven, focusing on consumer preferences and market needs. This involves developing varieties that not only have high yield and disease resistance but also meet the nutritional and culinary preferences of consumers. For example, breeding strategies that target market segments with high rates of malnutrition and vitamin deficiencies can have a significant impact on public health (Ojwang' et al., 2023). Additionally, understanding and addressing consumer preferences can help overcome challenges related to the commercialization of new varieties, ensuring that they are well-received in the market. By focusing on these future directions, sweet potato breeding programs in China can achieve greater success in developing varieties that are not only high-yielding and resilient but also meet the nutritional and market demands of the population (Lebot, 2020; Markel and Shih, 2021). 8 Concluding Remarks The utilization of genetic resources in sweet potato breeding in China has shown significant potential in addressing both agronomic and environmental challenges. Key findings from the reviewed studies highlight the importance of genetic diversity and phenotypic variability in crop improvement. For instance, the study on cultivated potatoes in China demonstrated a high level of genetic variation, which is crucial for breeding programs
