Abstract

Potential agroecosystems in terms of area but suboptimal from land productivity are lowland swamps and drylands. The main constraints to maize production in these two agroecosystems are low soil pH and soil nutrients. This obstacle will be more severe if there is a global climate change. Increasing the potential of local maize genetic resources is needed to address these constraints. The review aims to explore the possibility, problems, and efforts to increase the productivity of local maize genetic resources. The review method uses reference studies of different research results, especially those related to local corn varieties, research technology, and utilization in breeding programs. The results of a review of various references show that local maize productivity based on the implementation of existing technology is primarily determined by genetic, environmental, and management factors. Constraints of corn production in swampland and dryland will become potential by increasing local corn^s existence. Increasing local maize^s existence is used as a gene donor in creating stress-tolerant varieties (low soil pH and nutrients, inundation, drought, pests, and diseases). Increasing local maize^s existence is used as a gene donor in creating stress-tolerant varieties (low soil pH and nutrients, inundation, drought, pests, and diseases). The increased opportunity for local corn technology adoption can be done by refocusing research that explicitly uses tolerance and efficiency parameters. In the future, the expected research output is applicable technology

Keywords: local maize varieties, specific agroecosystem, cultivation technology
