Intraspecific hybrid generations inUrena lobata L. with a note on the taxonomy of the species

  • Published:
Proceedings / Indian Academy of Sciences

Abstract

Meiosis in the hybrids betweenUrena lobata ssp.lobata andUrena lobata ssp.sinuata was normal with 14 bivalents thereby indicating close homology of the two genomes. The inheritance of leaf lobing was studied in F1, F2 and F3 generations. It is seen that leaf lobing inUrena lobata is a monogenic trait with incomplete dominance. Evidence from this study supports the retention of the subspecies status of the taxa.
