Resumen de Interfertility in the genus "Moricandia" DC
The objective of this work was to outline a more natural taxonomy of the genus Moricandia DC. The possibility of obtaining experimental hybrids using most of the species of this genus was studied using a diallelic crossing table. A. moricandioicies and M Joetida, both endemic of the Iberian Peninsula, were found to have strong reproductive isolation. Hybrid seeds were obtained from the remaining species; however, as in M. suffruticosa x M. arvensis and M. spinosa x M. nitens, alterations in pollen fertility and pollen morphology studied under SEM, were found, showing important reproductive disorders. Thus, it is proposed to maintain this genus comprised of eight species: M. arvensis (L) DC., M. nioricandioides (Boiss.) Heywood. M. fbetida Bourg ex Coss., M.suffruticosa (Desf.) Coss, M. spinosa Pow!, Al. nitens (ii .) Dig: i& Batt., M. sinaica (Boiss.) Boiss and M. foleyi Batt. arvensis (L.) DC.var. rohusta Ban. must be included in the typical M. arvensis(L) DC.
