Distribution of essential oils in leaf tissue of an F2 population of Citrus
SummaryThe identification and distribution of 17 mono- and sesquiterpenes in an F2 population produced from selfing of an interspecific F1 hybrid is presented. A mode of inheritance for most of these components is attempted, percentages of leaf oil components and a correlation matrix are given.
Turpentine composition of Pinus contorta × Pinus banksiana hybrids and hybrid derivatives
Inheritance of turpentine composition in Pinus contorta × pinus banksiana hybrids has been studied on the basis of 7 pure Pinus banksiana trees, 17 pure Pinus contorta trees, 18 backcrosses to P. b...
The genetic basis of the ketones, carvone, and menthone in Mentha crispa L.
The molecular structure of carvone, the principal ketone of spearmint, differs from that of menthone, the principal ketone of peppermint, in two distinct respects. This difference is due to an allelomorphic change in a single gene with carvone (C) dominant over menthone (c). The suggested mode of gene action is that the dominant and recessive allelomorphs determine alternative methods of cyclization of a common antecedent ketone.
