Reciprocal Chromosome Translocations Without Semi-sterility

Abstract

Three different reciprocal translocations produced by radiation treatment in Triticum monococcum and 2 in T. darum have been studied. A plant which is heterozygous for any of them shows nearly normal fertility, both of seeds and pollen. This is due to a regular zigzag (Oenothera-like) segregation of the 4 chromosomes in the translocation ring.
