E l ‐A ni , A rif S., L. S. O live , and Y. K itani . (Columbia U., New York City.) Genetics of Sordaria fimicola. IV. Linkage group I. Amer. Jour. Bot. 48(8): 716–723. Illus. 1961.—A general technique for isolating and testing various morphological mutants induced by X ray is described. Eleven mutants differing in ascospore color, fertility, and rate and type of growth were studied in different crosses. This has led to the construction of the first linkage group in S. fimicola. The chromosome on which the 11 mutant loci occur is marked by a single locus on one arm and 10 on the opposite arm. The ascospore color mutant gray is autonomous, maintaining the mutant spore color in both homozygous and heterozygous asci, whereas milky , the other color mutant studied. expresses its mutant effect only in asci homozygous for the factor. Certain crosses involving 2 sterility mutants controlled by 2 non‐allelic loci are fertile, and the progeny give rise to parentals as well as double‐mutant and fertile recombinants.
