Genotyping by Sequencing for Plant Breeding- A Review

Breeding of crops can be accomplished through two major approaches i.e., conventional and molecular.Variety development through the former approach requires continuous hybridization between distinct parents and selection over several generations.Long time (5-12 years) to develop crop variety, genotype by environmental interaction, low efficiency for complex and low heritable traits are the major limitations of this approach [4,6,7].Applications of molecular biology tools that used to improve (develop) new cultivar is known as molecular plant breeding [8].Unlike conventional method, this method used in DNA marker for selection of a given trait.This method helps to increase the efficiency, speed and precision of plant breeding in which it reduced cost and time [7,9].
