Pearl millet is a crucial coarse grain crop that serves as a primary food source for impoverished communities in arid and semi-arid regions of Africa and Asia. These regions account for 98% of the world’s pearl millet production and cultivation, thriving in warm, tropical dryland environments. Characterized by its protogynous inflorescence and chasmogamous flowers, pearl millet is highly allogamous through wind, making hybrid seed production a key aspect of its cultivation. The development of hybrids involves creating a variety of trait-specific parent lines through recurrent selection, focusing on attributes such as grain yield and disease resistance. The cytoplasmic genetic male sterility (CGMS) technique offers a genetic approach for the commercial production of pure single cross hybrid seeds from an A-line and R-line cross under open pollination in isolation. Maintainer lines, also known as B-lines, are the equivalent of A-lines and have fertile cytoplasm but the same nuclear gene makeup. Open-Pollinated Varieties (OPVs) are randomly mated populations maintained in isolation to preserve genetic integrity. For successful seed production, adherence to strict standards is essential, including maintaining isolation distances, managing crop layout and planting ratios, ensuring seed quality, and addressing flowering synchronization, pest and disease management, and harvesting practices.
