Abstract:
Molecular markers are unique DNA fragments that can be identified inside the entire genome and are effective tools used to ‘flag’ the location of a specific gene or the inheritance of a definite trait. The development of molecular markers combined with high throughput technologies have paved the way for achieving the desirable traits as well as induced biotic and abiotic stress tolerance in plant, which enhanced the crop breeding. Highly polymorphic molecular markers are developed for gene mapping, estimation of genetic Diversity, finding out the evolution and phylogeny of crop, analysis of heterosis, assessment of diploid/haploid crops and genotyping of cultivars along with Marker Assisted Selection (MAS). This review reveals about the role of various recently developed molecular markers in the improvement of crop.
