Although databases for genetic resources have been developed, a comprehensive schema to manage such multiple subsystems as forestry, livestock, microbial, and aquatic germplasm has yet to be fully developed. Mexico's National Center of Genetic Resources faces the challenge of managing all of these subsystems; therefore, we projected an integral system to meet such demands. In this work, we present the first stage of implementing this system. We have developed a new schema and an input/output system for passport data that will improve the data management of multi-subsystem germplasm. This schema can unify all subsystems with a comprehensive identifier at the accession level. By establishing a sub-identifier, elements that were traditionally allocated as independent accessions would be set as a subgroup of the same accession. The sub-identifier allows variability in element treatments, facilitates diverse sample management, and avoids redundancy. The passport database is complemented by an effective insertion and retrieval system that will facilitate transition from the previous data management of individual subsystems to a subsystem-comprehensive database system.

Introduction Agricultural biodiversity has been defined as the diversity within biological elements that play a fundamental role in agricultural ecosystem structure and processes (Dulloo et al. 2010). The narrow genetic basis of breeding can be easily subject to catastrophic loss caused by natural disasters, drastic climate change, or epiphytotic disease (Altieri & Merrick 1987, Blackburn 2009). And because the risk of a significant loss of diversity has increased in recent years, animals, plants, and microorganisms have attracted global attention relative to food, agriculture, and the preservation thereof (Rands et al. 2010). The sustainable use and development of genetic resources are essential for stabilizing the world's food supply. Consequently, ex situ conservation aims to keep germplasm material alive as long as possible as a strategy to avoid the agrobiological loss of such genetic resources (Dulloo et al. 2010). Adequate genetic resource management in gene banks largely depends on the management of materials, human resources, budgets, and information about the materials (Clark et al. 1997). Such management should be conducted in accordance to the magnitude of a gene bank and the diversity of stored materials. Mexico is considered to be among the world's most mega-diverse countries (Mittermeier 2005). In 2012, the
