Policy Gaps and Practices on Genetic Diversity, The Heterogenous and Localized Evolutionary Population as well as Native Landraces in Agriculture of Nepal

Abstract

Formal breeding strategies and processes focus on developing uniform and non-evolutionary populations. However, many farmers continue to cultivate heterogenous cultivars and populations. To understand the recognition of genetic diversity (heterogenous cultivars and populations) in policies and the fields, a literature survey along with field survey, interaction and field action research were carried out in 15 districts of Nepal. Existing policies demand varieties to go through DUS (distinctness, uniformity, stability) testing and be registered in National Seed Board (NSB) for commercial production and sale. This means all native landraces and other broad genetic-based genotypes cannot be marketed without registration. A formal agriculture system accelerates the cultivation of a single genotype in a large area, leading to a lack of pollinators and the loss of many genetic diversities. Legal agricultural systems have focused mainly on modernizing agriculture through exotic resources, giving less priority to making native landraces and technologies globally competitive. In contrast, the informal seed system deals with polymorphic and evolutionary populations. Therefore, policies should consider the strategies that favor and increase genetic diversity, evolutionary population, site-specific genotypes and staple food, self-seed production system, ecological services, insects/birds/ microorganism-friendly systems, etc. Native agricultural genetic resources (AGRs) with broad genetic bases are essential for food, nutrition, health, environment, and business security. Therefore, native landraces of all six components of agrobiodiversity (namely crops, forages, livestock, aquatic genetic resources, insects, and microorganisms) should receive priority in research, development, extension, and education. Additionally, a favorable policy for the commercialization of such native landraces and/ or their products without registration should be established. Alternatively, a registration system should be developed for broad genetic base genotypes and heterogenous and evolutionary populations.
