“…The newer chemical types so developed offer the distinct advantage amenable for natural selection. The production of hybrid compounds in alloploids has been explained as the modification of the products of one parental genome by the genome of other parent (Alston et al, 1965;Fahselt & Ownbay, 1968;Levy & Levin, 1975;Mears, 1980). Probably, intergenomic complementation of the blockages/limiting factors attendant in the biosynthetic path-way of one parent by the other brings about such an effect.…”

Artificial polyploidy generally enhances the vigour of determinate plant parts and may be favourable where vegetative organs and biomass constitute the economic product. Giving suitable examples, it is shown that genomic multiplication can confer enhanced production and/or qualitative improvement in the biochemical profile of secondary metabolites. Allopolyploidisation can bring about natural complementation of biosynthetic pathways to harness the useful metabolites. A plea is made to utilise the induced polyploidy approach as a rapid means to attain enhanced production of secondary metabolites: pharmaceuticals, aroma chemicals, etc. The necessary prerequisites that may be needed for achieving genetic stability and reproductive success of the induced polyploids are outlined.

“…It is possible that some of these substances were new structural configurations, i.e., hybrid-specific compounds, formed by the combined enzymatic complements of the parents. Definitive experimental proof of hybrid-specific compounds in Baptisia has been reported by Alston et al (1965). In summary, it would appear that intergenomic recombination in Phlox can (1) effect the elimination of one or more substances associated with a species profile, and (2) effect the synthesis of new compounds.…”

“…The genus Baptisia with 16 clearly defined species (Turner and Alston, in preparation) is confined to the eastern half of North America. It has been investigated intensively by a group of workers at The University of Texas, especially as regards the systematic implications of the distribution of flavonoids in the genus (Alston et al, 1965;etc.). Most of this work has related to problems of interspecific hybridization (Alston and Turner, 1962;1963).…”
