IV. Why this course ?
Medicinal and aromatic crops play an important role in the national economy of
India. For the crop improvement programme of these crops, fundamental knowledge
on origin and development, evolutionary process, taxonomy and cytogenetics is
most essential. This course will impart theoretical knowledge to the learner on the
origin and distribution, evolutionary process, taxonomy and cytogenetics of various
medicinal and aromatic crops.
V. Aim of the course
To impart basic knowledge on the origin and development, evolutionary process,
taxonomy, cytogenetics and genetic resources of medicinal and aromatic crops.
