A review on linkage mapping for drought stress tolerance in rice

Abstract

Rice is one of the most widely grown cereal crops in the world and is the staple food of more of the world's population. Environmental degradation, including pollution, increase in night time temperature due to global warming reductions in suitable arable land, water, labour and energy dependent fertilizer provide constraints to rice productivity. Drought stress is a major abiotic threat to rice production and its yield stability which leads to production of drought tolerant rice cultivars. Linkage analysis will help us to identify the genes contributing to drought tolerance in rice and their relative contribution to the very important trait.
