Code(Credit) : ASPG3104 (1+1)

Course Objectives

• To understand the origin, distribution and different breeding methods to be adopted for the development of varieties / hybrids in various Kharif crops
• To study about the plant genetic resources, centres of diversity and breeding for resistance to biotic and abiotic stresses
• To learn about the influence of Genotype x Environment interaction on yield / performance

Learning Outcomes

By the end of this course students will imparted with knowledge on the botanical description, origin, distribution and various breeding approaches used for the development of varieties / hybrids in various Kharif crops
