Abstract

The increase in the potential of local rice genetic resources is very promising in responding to the challenge of increasing public awareness of functional food. The productivity of local rice genetic resources is still low, among others due to limited information and implementation of specific agro-ecosystem cultivation technology, and low utilization as genetic material in plant breeding programs. The review aims to explore the potential, problems, and efforts to increase the productivity of local rice genetic resources in the three main agroecosystems in Indonesia (dry land, swampland, and non-swamp wetland). The review method uses reference studies of various research results, especially those related to the variety of local rice varieties, existing technology, research technology, and utilization in breeding programs. The results of reviews from various references show that local rice varieties in the three agro-ecosystems are very diverse, especially in terms of several specific advantages, including sub-optimal environmental adaptability and high rice micro-nutrient uptake. Local rice productivity based on the implementation of existing technology is largely determined by genetic, environmental, and management factors. Support in the initiation of short-term research programs and long-term programs is needed to increase the productivity of local rice in the three agroecosystems. The expected outputs from implementing short-term programs and long-term programs in each agroecosystem are recommendations for local rice cultivation technology packages and new high yielding varieties.
