Abstract

Genetics is the science of studying the inheritance and variation of organisms. It is one of the biological disciplines that explore the rules of the structure, function, variation and transmission of genes. The concept and category of generation in plant genetics is a simple issue, but the usage of generation symbols is arbitrary so far. Different symbols are often used to express the same type of hybrid offspring, such as the traditional hybrid expressed in F1 or F0, and the regenerated plants in the tissue culture are expressed in R or R0 or R1, which leads to the fuzzy basic concepts of genetics. According to new generations generated by different methods and their genetic composition, the paper puts forward some suggestions to apply symbols to the new generation, so as to facilitate the study and research of plant genetics.

Key words： plant genetics; metagenesis; new generation; genetic composition; generation symbol
