Fischbeck and Hauser have located three genes on chromosome 3 by use
of three interchanges, T 2-3f, T 3-7c and T 3-7d. One of them is gran-a
for a small kernel character involved in a mutant 1024/65, which was later
indicated to be on the short arm of chromosome 3 by a further test with
Tsuchiya's telotrisomic 3 S. Two other genes are those for leaf spotting
mutants, 728/63 and HLN EP71-48. A mutal cross between these two indicated
that they were independently inherited with each other.
Moriya and Takahashi (1980) added to this linkage group two more genes,
sca for short, crooked awn and wst,,j for white stripe. According
to their data, the gene sca is very closely located with al
and inferred to locate between yst-2 and Rh. The gene wst,,j
was found to be on the opposite side of al as seen from uz,
and judging from the hitherto established linkage map for chromosome 3,
its location might be between rnt* and Yd2. For details please
