Multi-Crop Passport Descriptor

Multi-Crop Passport Descriptor is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Multi-Crop Passport Descriptor rather than just read about it. In short: The Multi-Crop Passport Descriptor (MCPD) is an extension to the international standard to facilitate germplasm passport information exchange. MCPD was jointly developed by the International Board for Plant Genetic Resources (now Bioversity International) and the FAO.

Key takeaways

Multi-Crop Passport Descriptor belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Multi-Crop Passport Descriptor to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Multi-Crop Passport Descriptor from memory before moving on to harder problems.

Reference excerpt

The Multi-Crop Passport Descriptor (MCPD) is an extension to the international standard to facilitate germplasm passport information exchange. MCPD was jointly developed by the International Board for Plant Genetic Resources (now Bioversity International) and the FAO. The Multi-Crop Passport Descriptor is intended to provide a standardised method of describing and exchanging information about plant genetic resources. The Multi-Crop Passport Descriptor includes plant descriptors such as, including scientific name, common names, growth habit, reproductive type, and disease resistance. It also includes descriptors for morphological and agronomic traits, and genetic and cytogenetic characteristics. The Multi-Crop Passport Descriptor also includes information about the origin and distribution of the plant, and its current use and potential uses. The descriptors are compatible with Bioversity's crop descriptor lists, with the descriptors used by the FAO World Information and Early Warning System (WIEWS) on plant genetic resources (PGR), and the GENESYS global portal.

Worked examples

Example 1 — a first encounter with Multi-Crop Passport Descriptor

Start with the simplest possible case. Write down what Multi-Crop Passport Descriptor claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Multi-Crop Passport Descriptor before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Multi-Crop Passport Descriptor ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Multi-Crop Passport Descriptor

In research: Multi-Crop Passport Descriptor appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Multi-Crop Passport Descriptor in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Multi-Crop Passport Descriptor is common in secondary-school and first-year university syllabi. It links to neighbouring topics Agriculture stubs, Crop protection, so understanding it makes those chapters shorter.
In everyday life: Look for Multi-Crop Passport Descriptor outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
