Trait Study
Sprouting, Anderson93
Trait
Wheat sprouting
Reference
ReferenceAnderson JA et al. (1993) RFLP analysis of genomic regions associated with resistance to pre-harvest sprouting in wheat Crop Science 33:453-459.
Protocol
Five physiologically mature spikes examined under artificial rainfall rated on 0 to 9 scale for degree of sprouting. Data was transformed so that all genotypes harvested from the same environment on the same day were equalized to an average of 1.0. Lower numbers indicate more resistance to preharvest sprouting.
