Abstract: This invention relates to methods for constitution and production of colony varieties of crops. Its characteristics are shown below. According to their phenotypes, single-genotype varieties, hybrid combinations or mixtures of varieties and combinations from fundamental populations, which are consistent or uniform in major characters and share particular breeding goals, will constitute the colony varieties of crops. The said single-genotype varieties or hybrid combinations are multiplied separately. According to the breeding goals, their seeds are mixed in a specific ratio to form the preparations for planting. The varieties produced in such a way are featured with uniformity, stability and peculiarity.
