Title	The linkage relations of four genes in Chromosome I of barley
Journal	Agronomy Journal
Year	1944
Volume	36
Pages	429-435
Author	Swenson S Wells D
Abstract	The inheritance of linkage relations of tall vs short plants and high vs low number of rachis internodes were studied in relation to two known marker gene pairs in chromosome I of barley, non-six-rowed vs six-rowed spikes (Vv) and awnless vs awned outer glumes (Ee) Plant height was found to be governed by one main gene pair, Hh, and a modifier pair, H1 h1 However, Hh could be satisfactorily isolated so its linkage relations could be studied. Rachis internode number also was conditioned by one main gene pair, Rin rin, and a modifier pair, Rin1 rin1. Furthermore, Rin rin could be isolated for a study of its linkage relations. The order and recombination percentages of the four genes were found to be v - 17.1 - rin - 12.8 - h - 8.1 - e. The addition of rin and h to the map of chromosome I increases the number of mapped genes to nine which occur in the order tr - v - rin - h - e - y - f - lg - or.
