Genetics of wood characters of black spruce (Picea mariana (Mill.) B.S.P.) in Newfoundland, Canada
The variation and relative control of genotype and envi ronment over 11 wood characters in black spruce (Picea mariana (MILL.) B.S.P.) were studied to identify populations with superior pulping qualities. A four- and three-level cluster sampling scheme was adopted and the statistical and genetic an...
