An Overview of Seed Production Methodologies in Selected Flowering Annuals

Abstract

This review provides a comprehensive overview of flower seed production, emphasizing the significance of the floriculture industry. Flower crops, especially annuals, contribute significantly to the beautification of surroundings and have become a lucrative agricultural business globally. The demand for quality flower seeds has led to the establishment of production facilities, particularly in India, catering to both domestic and international markets. The climatic requirements for seed production vary across different flower crops, with considerations for mild, sub-tropical, and tropical climates. The review delves into the nature of pollination for various flower crops, emphasizing the need for isolation to prevent contamination. F1 hybrid seed production is discussed, highlighting its merits and demerits, along with techniques for creating cross-hybrid seeds. The agronomic principles involved in hybrid seed production, including variety selection, seed pre-conditioning, planting time, sowing methods, and density, are detailed. The role of plant growth regulators, irrigation, and nutrition in optimizing seed yields is explored. Harvesting methods and the critical importance of proper timing are addressed, along with insights into seed storage conditions. The review concludes by emphasizing the multifaceted aspects of flower seed production, from climatic considerations to agronomic practices, pollination, and post-harvest processes. The knowledge presented serves as a valuable resource for practitioners and researchers in the floriculture and seed production sectors.
