One new numbered locus has been assigned to the genetic male sterile series (Table 1). These results of crossing a homozygous male sterile plant with a heterozygous male sterile plant show that the spontaneous mutant msg35dr is not allelic with any of the previously numbered loci. The msg35dr male sterile stock number 366 behaves as a single recessive gene and did not set any selfed seed when bagged at Bozeman (1). Karl msg35dr is the mutant used in setting up the male sterile facilitated recurrent selection population for 6-rowed malting quality (2).
