Part 3 of the original rules states "Mutant genes are designated by letter symbols. The mutant name comprises an adjective or noun or combination of both that refers to the main diagnostic feature of the phenotype. The initial letter of the symbol should be the same as that of the name; additional appropriate letters are added as necessary to distinguish it from other symbols already in use." Although this is a clear statement, it has not been adhered to in some recent instances, and amplification is needed to meet some newly arisen situations. We hope that before publication of a new symbol, the corresponding gene will be checked for allelism with other genes of similar phenotypes for duplication of previously existing symbols, and for conformity with the adopted rules.
The following rules have therefore been propos6d to clarify tomato gene nomenclature. We urge all members to adhere to them in order to minimize confusion and to improve the naming and symbolizing of new mutants.
1. Special effort should be expended to find appropriate names for new mutants. (Latin names or their English derivatives are recommended for their international meanings although this matter obviously cannot be made mandatory.)
2. The symbol should consist of no more letters or numerals than necessary to distinguish it from all other existing symbols. (Lengthy symbols may have reference value to the discoverer, but are of no significance to other workers who are often likely to make greater use of the mutants than the discoverer. When the length of the symbol approaches that of the name from which it was derived, it no longer is a symbol and becomes too cumbersome for genetic notation.)
3. Symbols for mimics of a single series should not be composed of various permutations of the letters of the same name. If a name is adopted for a series of mimics, all members of that series should be designated by the same name and symbol with proper numerical subscripts.
4. Much confusion will be avoided by clearing names and symbols with the Chairman of either the Gene List Committee or Coordinating Committee at the earliest opportunity. (Such action will settle matters of priority and assist the investigator by assigning a reasonably permanent symbol to his mutant. Permanence cannot be guaranteed because unknown earlier or simultaneous publication might establish priority.)
Since the 1954 list was issued at least 172 new genes have been reported. These are included in Table II below, together with references, seed sources, and descriptions. Table I contains a condensed version of the TGC 4 list.
Symbols in both lists have been revised when subsequent tests have indicated allelism, symbol conflicts have occurred, or symbols have not followed the revised nomenclatural rules. Parentheses following the preferred gene symbol contain synonyms or former designations. Where no priority symbol is listed, the parentheses enclose genes quantitative in expression or genes of doubtful existence. As in the 1954 list TGC references cite report and page number.
Wherever possible two independent sources have been located for each gene. Some of the Cooperative members kindly offering to supply these genes have not heretofore stocked them. Such sources will not be able to supply seeds until after the 1959 field harvest. Anyone willing to stock genes presently having only one source should contact C. D. Clayberg. All assistance will be greatly appreciated.
Descriptions note only the main characters. More complete accounts are frequently given in the references.
