Male sterility has provided new avenues for exploitation of heterosis and hybrid seed production in pigeon pea (Cajanus cajan L. Millspaugh). Finding of genic male sterility laid the foundation of commercial hybrid seed making in pigeon pea, resulting in commercial release of five hybrids in India. However, the Genetic Male Sterility (GMS) system was soon abandoned due to its high production cost. Later, identification of cytoplasmic male sterility (CMS) overcame crucial bottlenecks associated with the GMS system. The latest pigeon pea hybrids based on CMS system are IPH 15-03 and IPH 09-5, which are suitable for deployment in pigeon pea-wheat rotation system. The seed of newly released superior hybrid varieties should be available at the farmers doorstep before the onset of cropping season to ensure maximum benefits to the farming community. Multiplication of hybrid seed and its parental lines remains a herculean task. Successful seed production relies on several factors, and the present chapters describe crucial aspects of quality seed production of pigeon pea including floral biology, good agronomic practices, management of biotic and abiotic stresses, breeding behaviour, classes of seed and their requirement and post-harvest management and packaging of seed.
