Course Objectives

  • To impart knowledge to the students on the principles and procedures of plant breeding in self and cross pollinated crops for development of the high yielding varieties / hybrids with the help of various conventional and modern molecular approaches.

Learning Outcomes

  • • Learn breeding procedures in self and cross pollinated crops
    • Understand exploitation of heterosis utilizing male sterility and other methods
    • Know about the various population improvement programmes
    • Study about the fundamentals of mutation, polyploidy and wide hybridization and their role in crop improvement
    • Orientation regarding modern molecular approaches like Marker Assisted Selection
