**Abstract**

Radish is a member of the Cruciferae family. The important traits for radish breeding include high yield, early maturity, late bolting, pungency, cold-hardiness, drought resistance, heat tolerance and soil adaptability. For successful radish production, one needs to the understand nature and behaviour of the flower and very important to identify the S haplotypes of parental lines to produce F1 hybrids based on self-incompatibility to get rid of laborious hand emasculation in radish. Therefore, further breeding programmes depend on inter-specific and intra-specific hybridization, which is vital in genomic studies and crop improvement by introducing desirable agronomic characters. It is essential to acquire detailed genetic information on chromosomes and inheritance. Genomics is now at the core of radish breeding to study the underlying differences in genotypes. Moreover, researchers have produced transgenic radishes with various agronomic characteristics over the last decade.
