Trait Study	Sprouting, Anderson93
Trait	Wheat sprouting
Reference	Anderson 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.
Parental Description	Clark's Cream High resistance NY6432-18 Moderate resistance
Parental Mean SD	Clark's Cream 0.38 0.21 NY6432-18 0.89 0.4
Map Data	Wheat sprouting markers
Population Size	78
Population Type	F5-derived recombinant inbred lines
QTL Analysis Method	Single-factor ANOVA
Statistics	Population mean 0.97 [ Show all 11 ]
Heritability	0.84 line mean basis 0.35 per plot basis
Type I error rate per locus	0.05
Markers Tested	37
QTLs Found	4
Phenotypic R2	0.37
Genetic R2	0.44
R2 Definition	R-squared is the proportion of the total phenotypic or genetic variance explained by a multiple regression model containing the significant QTL and their interactions.
