Course objective

To educate students about the different breeding techniques used to create variations and hybrids in diverse field and horticultural crops (Rabi Crops), including their origin, distribution, and botanical description

Course outcome

CO-1: Students understand the value of using wild relatives to generate novel types of rabi crop in this course.

CO-2: Learner acquires knowledge of gene preservation technique to subsequently utilise to enhance Rabi crops.

CO-3: The student learns how to use breeding techniques to enhance Rabi crops.

CO-4: The student acquires knowledge about the use of genes and the identification of resistance genes related to Rabi crops with high production potential against pests and pathogens.
