Research Interests

Molecular breeding aims at the genetic enhancement of crops through the application of principles of Mendelian Genetics and modern tools and techniques of cell and molecular biology. Many breeding programs also include induced mutations with either or both physical and chemical mutagens and focus on the improvement of traits such as high yield, multiple resistance to major disease, insect pests and tolerance to abiotic stresses and improved quality.


In our R&D work, we focus on development and deployments of genetic/genomic resources for crop improvement in linseed which is an industrially important crop. The genetic resources include germplasm, core-germplasm, MAGIC population, RILs population and mutant populations of aforementioned crops. Germplasm and core-germplasm of linseed consists a diverse set of accessions for oil and fibre traits which were evaluated for phenotypic variability and utilized in association studies.

Research Summary

Several bi-parental mapping populations (Recombinant Inbred Lines) of linseed have been developed and are being utilized for linkage/QTL mapping.Further, eight parent based MAGIC (Multiparent Advance Generation Inter Cross) populations in linseed are also in developmental stage. To create induced variability, EMS mediated mutagenesis have been attempted in linseedand a large population of mutant lines developed.


The genomic resources consists of a large set of molecular markers (SSR, SNPs) developed in linseed. SSR markers-based diversity assessed in 168 accessions of linseed and a set of diverse accessions identified for genetic improvement of linseed.SSR based linkage/QTL map of linseed have been developed and QTLs for Alternaria blight resistance identified through QTL mapping and through BSA (Bulk Segregant Analysis). The SNP markers based genetic diversity and association studies havealso been carried out which revealed several potential QTLs associated with important agronomic traits.
