Is it essential to retain indigenous varieties when many hybrid
varieties are available?
Answers
Answer:Hybrid crop varieties are often criticized by environmental NGOs (e.g. Navdanya in India; Arche Noah in Austria) for various reasons: seed to seed propagation is problematic; hybrids have high yields and are homogenous in pehnotype but require much input (fertilizers, pesticides etc.).
According to these NGOs hybrid varieties are also threatening agrobiodiversity because a few hybrid varieties outcompte a broad range of seed-to-seed varieties.
My current understanding is that hybrids are good for an industrialized (organic) agriculture but that non-industrial production conditions require different varieies growing under suboptimal/low input conditions.
Likely you have some good supllemental or contradicting knowledge on that issue.
