Conventional and non conventional approaches of plant breeding
Ph.D (Genetics and Plant Breeding)
  • Concept of Pollen Based Selection (PBS) was developed as an alternate strategy to overcome breeding problems in vegetatively propagated crops.
  • Molecular makers in protection of plant varieties has been analysed utilising rose and carnation, two commercially important flower crops as model plant species. 
  • Alternate approaches for creation of variability utilizing tissue culture as a tool in vegetatively propagated species have been developed. 
  • Reducing the duration of breeding cycle in rose is one of the challenging fields we are working on. 
  • Male sterility in marigold, its maintenance, inheritance pattern and utilization is another area where in significant progress has been made.
