Optimizing Hybrid Sorghum Seed Production: Key Challenges and Future Opportunities
摘要
Sorghum (Sorghum bicolor L.) ranks as the fifth most important cereal crop globally and thrives particularly well in dry and semi-arid climates. The advent of hybrid seed production has transformed sorghum cultivation by significantly boosting yields. This transformation is not limited to India but extends to other major sorghum-producing regions globally. Hybrid sorghum’s potential lies in combining advanced breeding methods with genetic diversity to produce varieties suited to specific environmental conditions and farmer needs. Hybrids with enhanced drought resistance can mitigate water scarcity effects, while those with improved disease resistance can reduce dependence on chemicals, promoting sustainability. Despite these benefits, hybrid sorghum production faces challenges, including maintaining genetic purity of parental lines, effective pollination control, high production costs, and socio-economic barriers affecting smallholder farmers. This chapter delves into the current state of hybrid sorghum seed production, highlighting key challenges such as male sterility, disease management, optimal field selection, and synchronized flowering. It also explores future opportunities, including advances in technology, harnessing genetic resources, and socio-economic and environmental benefits. By addressing these challenges and leveraging emerging opportunities, stakeholders can enhance the adoption and effectiveness of hybrid sorghum in diverse agricultural systems.
