Rainfed lowland rice improvement

This book, which consolidates and shares knowledge on rainfed lowland rice improvement gained by researchers over the past two decades, follows the pattern set by Rice improvement, a classic manual published by IRRI in 1979. While all aspects of a rice improvement program are considered, the main focus is on rainfed lowland rice. The 14 chapters cover three distinct areas: 1) the defining components of rainfed lowland environments, i.e., the ecosystems and the cultivars; 2) typical and appropriate objectives for rainfed lowland breeding programs, including agronomic or morphological traits, growth duration, drought resistance, submergence tolerance, low temperature tolerance, adverse soils tolerance, disease and insect resistance, and grain quality; and 3) breeding procedures: selecting parents and making crosses, managing segregating generations, evaluating advanced breeding lines, and releasing varieties. New techniques in biotechnology are briefly covered. These techniques will require the use of conventional rice breeding procedures covered to capture their impact.
