Rice is the source for more than 20% of the total calorie intake for more than half of the world population. More than 90% of it is produced and consumed in Asia. Chronically food-deficit Asia became self-sufficient in this crop by the early 1980s following the introduction and extensive adoption of high-yielding varieties with dwarf plant type starting in the mid-1960s. To sustain this self-sufficiency, it is esti-mated that the global rice requirement by 2050 will be 70% more than what is pro-duced now (Fig. 1). Meeting such a huge demand projection sustainably in the face of the shrinking favorable growth of the 1970s and 1980s, especially for natural resources such as arable land, irrigation water, and genetic resources, is the most challenging task ahead. This situation warrants the discovery of novel gene sources and innovative breeding-selection strategies to develop varieties that would enable the world to meet this challenge.Systematic breeding for the improvement of Asian rice (Oryza sativa L.), although begun more than a century ago, has been witnessing rapid advances for the past 60 years, with landmark achievements in both applied and mission-oriented basic research. In keeping with the objective of this publication, “Molecular and physiological breeding strategies toward sustained self-sufficiency in rice,” this introductory chapter offers an overview of the significant achievements made during this period. Raising the ceiling for genetic yield had been the major breeding objective until the 1950s, when Chinese breeders succeeded with the first-ever dwarf variety, Guang-Chang-Ai, using the spontaneous dwarf mutant Ai-zi-zhan (Huang 2001), followed by Taichung (Native)-1 in Taiwan using yet another spontaneous dwarf mutant, Dee-Gee-Woo-Gen. Impressed with its yield performance and period-bound matu-rity, the International Rice Research Institute (IRRI), using the same dwarfing gene source in a cross with tropical japonica variety Peta, developed the miracle yielder, IR8, by the mid-1960s. The extensive adoption of this variety and its derivatives heralded Asia’s Green Revolution.
