Associated in the development of pumelo and mango varieties. Developed a method to identify the nucellar seedlings in polyembryonic mango varieties using leaf volatiles. Assessed the stigma and pollen metabolites in mango varieties differing in fruit set like Totapuri, Amrapalli, Alphonso, Arka Anmol, and Arka Puneet. High fruit setting types were found to have better salicylic acid, GA, IAA, higher polyamines and lower phenolic acids in both pollen and stigma. Metabolites and flower minerals were found to improve under irrigation. Volatiles produced by different bioagents were also assessed. Esablished the GCMS/MS facility under central facility of the institute. Assessed more than 10,000 samples under SAIF facility of the institute. Generated more than Rs 15.00 lakhs revenue.Guided 3 MSc students UAS, GKVK for Crop Physiology. Guidng 1 PhD student. Published 25 papers, 3 book chapters, attended various seminars/symposia/conferences, gave lead lectures.
