Grego

Grego is latin for "to gather or assemble" [1].

Similar to grex breeding except it consists of a mix of interbreeding and non interbreeding relatives. The reason for this is to strengthen genetics and imporve efficiency above what grex farming can.

From hybrid: "DNA can be absorbed by roots and pollen tubes [2] and self dna harms plants [3] thus the need for crop rotation and shabbat (shmita) weed growth."

What this means is that simple grex plant growth over many generations can harm long term growth efficiency. Adding extended non-breeding varieties (grego) to the interbreeding varieties can provide adaptive genetic traits through dna sharing through the roots and pollen transfer even if they can't naturally cross, and also this reduces self-dna in the soil which self-dna harms efficiency.

An example could be growing multiple species of tobacco together.

Another example would be growing pumpkin of Cucurbita maxima, Cucurbita moschata, and Cucurbita pepo varieties together.

Grex

This differs from grego in that grex only includes varieties that will interbreed directly with eachother.

Grex means "flock" in latin.

A mix of interbreeding varieties or species to enhance plant genetics.

Minimal trait requirement selection (MTR)

Minimal trait requirement (MTR) is a process for seed selection that is as genetically inclusive as possible. A minimum set of requirements for plant/fruit/seed traits is set and all seeds that are from plants/fruit that meet those requirements can be saved.

For example for naked or hulless pumpkin seed selection one could set a MTR of hulless seeds, disease resistance, and reasonable yield. Then seeds from all plants/fruit that meet those requirements could be saved for sowing next season.

The reason why this would be done instead of selecting for and maximizing certain traits is firstly to keep as much genetic diversity as possible. Different farmers want different traits so they can take an MTR version and further refine it for their specific requirements. Another reason could be for seed companies to have as much seed in stock as possible, so less stringent requirements mean more seed can be put on the market.
