Path coefficient and genetic divergence analysis for germplasm selection in aerobic rice (Oryza sativa L.)

Abstract

In temperate areas, rice production may benefit from rising temperatures. However, in the majority of the world’s rice areas, crop production will suffer as a consequence of climate change unless measures for improved crop adaptation to rising temperature, submergence, salinization or drought are taken. Because of increasing water scarcity, there is a need to develop alternative systems that require less water. The above challenges can be met by exploiting genetic resources with conventional and biotechnological approaches to produce highly productive and well-adapted varieties. To mitigate threats to productivity posed by intensification, diversification, water shortages and climate changes will require innovative approaches to develop resource management and germplasm options
