Origin and evolution of tetraploid forms within theSolanum nigrum L. complex

  • Published:
Proceedings / Indian Academy of Sciences

Abstract

Autotetraploid ofS. americanum (D1-col) was compared with the diploid progenitor,S. americanum Mill (=S. nigrum 2x) (D1) and the natural tetraploid,S. villosum Mill (=S. nigrum 4x) (T1). The study based on morphological comparison,t-test of interpopulation differences in mean values, discriminant analysis,D 2 analysis, amino acid-, flavonoid-and sugar-analyses clearly pointed out that autotetraploid has more affinity with the natural tetraploid than with its diploid progenitor leading to the conclusion that autopolyploidy might be significant in the evolution of tetraploid forms within theS. nigrum complex.
