QTL mapping for abiotic stress tolerance in maize: A brief review

Abstract

In this review article, we describe various QTLs that are associated with abiotic stress tolerance in maize. As we know, as global climate is becoming unpredictable and erratic. Yield in maize is affected by abiotic stress caused by unfavourable environment. So, exploiting QTLs associated with abiotic stress is the one of the way to achieve yield increase in maize. This review tells how QTL-based approaches has helped in improving the maize crop to perform well under various kinds of abiotic stresses. Success can be achieved by the identification of large effect QTLs that are linked with abiotic stress tolerance related traits. The QTL approach therefore provides a way to investigate out the various components affecting source sink relationships of maize plants under abiotic stress.
