AGR 013 ECONOMIC BOTANY AND PLANT GENETIC RESOURCES                                                                                 (1L+1P) III

Objective
This course is aimed at understanding the economic uses on plant species and potential of plant species as a natural resource or raw material for use in crop improvement.

Theory

UNIT I
Origin and history of agriculture; dynamics of domestication; centres of plant origin and diversity.

UNIT II
Patterns of variation; classification of cultivated plants; concept of gene pool; geographical distribution of crops of Indian origin.

UNIT III
Principles of PGR exploration and collection; introduction, acclimatization and utilization; principles of plant quarantine; principles and strategies for germplasm conservation; ex situ and in situ methods.

UNIT IV
Components of genebank: seed genebank, field genebank, in vitro repository, cryo genebank; DNA libraries, herbarium.

UNIT V
Policy issues: assessing economic values, conflict over ownership, management and use; data documentation.

Practicals
Preparation of herbarium; recording the data for characterization and evaluation of genetic resources in the field; Processing of samples of genetic resources for long-term conservation: testing the viability and seedling vigour, testing of  moisture content, equilibration of  moisture content, packaging of sample for long-term conservation in Seed Genebank; in vitro conservation of genetic resources: preparation of culture medium, sterlization and inoculation of explants, maintenance of cultures in the In vitro Genebank; data documentation, demonstration of database on plant genetic resources.
