PGR 504 PRINCIPLES AND PRACTICES OF GERMPLASM REGENERATION AND EVALUATION                                             (2L+1P) II

Objective

To educate students about science of managing genetic resources including principles involved in maintaining genetic integrity during regeneration, germplasm characterization and evaluation.

Theory

UNIT I
Grmplasm management systems: global scenario; genetic variation in crop plants and management of germplasm collections.

UNIT II
Principles and practices of germplasm regeneration and maintenance, breeding systems and mode of reproduction; maintaining sufficiently large populations for effective conservation of farmer landraces.

UNIT III
Germplasm characterization/evaluation procedures; evaluation of germplasm for specific traits; key issues for the improvement of characterization, evaluation and use of plant genetic resources; concept of core collection.

UNIT IV
Measuring diversity using agromorphological data; gene markers and their use in PGR management.

UNIT V
Evaluation and maintenance of wild relatives of crop plants; genetic enhancement/pre-breeding and use of alien/unadapted genetic resources in crop improvement.

Practicals
Field layout and experimental designs, recording field data on germplasm evaluation in different agri-horticultural crops, biochemical and phyto-chemical evaluation of crop germplasm, data processing, documentation, analysis of diversity and cataloguing.
