Gene Class

Gene
Sh2 (Hordeum)
Germplasm
Germplasm Igri (barley) Laurie DA et al. (1995) RFLP mapping of five major genes and eight quantitative trait loci controlling flowering time in a winter x spring barley (Hordeum vulgare L.) cross. Genome 38:575-585.
Phenotype
In DH lines derived from an Igri x Triumph cross, increased flowering time (days to heading) in unvernalized plants, but not in plants that had undergone a vernalization treatment (5 degrees C, 8h light for 6 wk). Model fitting revealed a 1.1d delay in spring-sown plants but none in autumn-sown plants (1).
Property
Recessive
Interactions
Presence of sh allele (and possibly Ppd-H2 Triumph-type allele) mask effect of this Sh2 allele. Allele interacted with eps2 'earliness per se' QTL in autumn-sown and spring-sown field experiments, and also with eps7L (1).
