Our lab is working on genomics and marker assisted breeding
-Developed microsatellite markers for mango, banana, okra, pomegranate, Garcinia speceis and sapota.
-Invovled in gene pyarmiding and development of tomato hybrids.
-Assessement of genetic diversity and characterization of Indian mango cultivars
1. Functional Genomics of Fusarium wilt and drought tolerance in Banana
2.Functional genomics of plant type, maturity and fruit quality traits in mango
3. Introgression of Begomovirus Resistance Genes in Tomato (Solanum lycopersicum L.) Through MAS and Genomic Approaches.
4. NICRA- Heat tolerance studies in tomato
5. Molecular analysis of mode of action of microbial inoculants(MIs) employed for enhancing plant growth and imparting tolerance to biotic stress
6.Screening of Banana germ plasm from the NE fm· Fusarium wilt resistance and mofteculat· characterization in contrasting genotypes
