नीचे दिए गए विकल्पों में से सही उत्तर चुनिए:
Objectives of Plant Genetic Resources (PGR) Conservation:
- Plant genetic resources represent the fundamental reservoir of genes providing resistance to diseases, pests, drought, and climatic extremes.
- The primary objectives defined by FAO and NBPGR are:
- Safeguarding genetic diversity for future generations (A): Preventing genetic erosion and loss of landraces and crop wild relatives.
- Ensuring global food security and agricultural resilience (D): Providing genetic variation to breed resilient, nutritious crop varieties.
- Facilitating breeding research and innovation (E): Supplying novel alleles for yield enhancement and climate-smart agriculture.
- PGR conservation aims to prevent the hazards of genetic vulnerability caused by monoculture (B is completely contrary to conservation goals). Eradicating invasive weeds (C) is a weed management / ecological restoration goal, not the mandate of PGR conservation.
Therefore, (A), (D), and (E) are the valid primary objectives.
Correct Answer: Option 2 ((A), (D) and (E) only).
