Studies Concerning the Inheritance of Ascospore Length in Neurospora Crassa I. Studies on Large-Spored Stra,Ins

Abstract

Previous work has shown that the inheritance of ascospore size in certain strains of Neurospora crassa is controlled by a polygenic system with a small cytoplasmic component. Various types of selection lines were set up in strains that had been selected for the large· spored character. The results of these selection procedures are discussed. Experimental work which gives a better estimate of the linkage of part of this polygenic system to the albino locus on chromosome I is reported.
