Title	The character brown ear of wheat: A review.
Journal	Euphytica
Year	1983
Volume	32
Pages	299-310
Author	Zeven AC
Abstract	A summary of the brown ear character of bread wheat is presented. In most varieties this character is conditioned by a (semi)dominant gene identified as Rg on 1BS. This gene seems to be widespread, from the viewpoint of evolution, probably because it is an 'old' gene. There are no indications that the presence of the gene and hence the presence of a brown ear is advantageous or disadvantageous to the carrier wheat plant. Some linkage relations are described. More research is needed to establish whether all varieties with one gene for brown ear carry Rg, to investigate the varieties with a non-monogenic genetic system and to identify more associations between brown ear and other characters. It should also further be investigated whether within T. spelta another gene for brown ear is present and, if so, whether this gene is on chromosome 1AS and linked to Hgl, the gene for hairy glume.
