摘要/Abstract

摘要：

遗传学是研究生物遗传与变异的科学,是探索基因的结构、功能及其变异、传递规律的生物学学科之一。植物遗传学中世代概念和划分尽管是一个简单的问题,但至今世代符号的使用仍然存在随意性,经常会出现利用不同的符号表示相同类型杂交后代的情况,如传统杂交后代以F₁或F₀表示,组织培养当代植株以R,R₀,R₁表示,从而导致遗传学基本概念的模糊。根据创建新世代的方法和遗传组成进行定义,本文提出了不同方法产生的新世代应用符号的建议,以便对植物遗传学领域的学习和研究提供借鉴和参考。

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 R₀or 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
