Dr  Khosa did his B.Sc and M.Sc. from Punjab Agricultural University, Ludhiana, India. He completed my Ph.D. from University of Otago, Dunedin, New Zealand. After Ph.D. He worked as a post-doctorate fellow at University of Wisconsin, USA. In March, 2020, DrKhosa joined Punjab Agricultural University, India. He loves to play and watch different sports and reading anything interesting outside academia. 

Research Interest:

Plants respond to different exogenous (day length, temperature, and light) and endogenous cues (sugars and hormones) to regulate multiple developmental stages. My research is focused to understand how flowering and storage organ formation is regulated by different exogenous and endogenous cues. In addition, we are interested in following areas:

• Bulbing and flowering regulation in onion
• Epicuticular waxes biosynthesis and their role against biotic and abiotic stresses
• Utilization of genome editing for cultivar development
• Cytoplasmic male sterility and hybrid development
• Vitamin A and seed coat biosynthesis in pumpkin

Project Accomplished

Identification and characterization of Pre-mature bolting genes responsible for pre-mature bolting in tropical onions grown in India (DST, India)

On Going Projects:

1. Molecular mapping of fertility restorer gene in brinjal (Solanummelongena L.) from DST, India
2. Fine mapping of begomovirus resistance governing loci (qMI-Sq/To7.1 and qMI-Sq/To17.1) in Cucurbitamoschata (Duch.) from DST, India
3. Mitigating Abiotic Stresses in Potato and Onion Through Crop Improvement Approaches (NDMF, India)
