Female Strobili Incidence In a Minnesota Population of Black Spruce: Heretibility and Correlation With Height Growth

Significant family variation in female strobili incidence, ripenessto-flower and production were found in a Minnesota black spruce ( Picea mariana (Mill.) B.S.P.) population tested at four locations. Heritability estimates indicated that gain in early flowering from selection would be possible. Height growth through age 12 years was positively correlated (genetic and phenotypic) to female strobili production between ages 10 and 12 years.
