The famous “green revolution” of the middle of the twentieth century saved millions from hunger through large-scale introduction of high-yielding input-intensive dwarf varieties of wheat and rice. However, due to over emphasis on extending the green revolution activities across the countries, the rainfed areas were ignored from allocating not only necessary inputs but also the attention of researchers, extension agencies, and policymakers. Consequently, the ill effects of these development errors started appearing on the production and productivity of legumes. This scenario started threating the nutritional security of poor masses. In such rainfed areas, usually legumes and coarse cereals are cultivated under subsistence agriculture. Among the legumes, known for their high nutritional value, pigeonpea (Cajanus cajan (L.) Millsp.) is the most favorite and versatile crop due to its various farmer-friendly properties, including adaptation to different environments and cropping systems. However, the major issue of this crop is its plateauing low yields, and for a long time, it has been a subject of worry. In order to break this yield barrier in pigeonpea, the breeders explored the cytoplasmic nuclear male sterility (CMS)–based hybrid technology. Although this approach showed positive results with 30%–50% yield advantage over the best cultivars, some critical issues still persist. In this chapter, the authors have tried to identify the major traits, which are linked to adaptation and resilience, besides the grain yield of pigeonpea hybrids. These parameters may be enhanced by integrating modern genomics tools and empirical plant breeding methods.
