Description
Lack of or limited knowledge of 1he breeding systems of most of the Vicia speci1;s in the National Plant Germplasm System (USA) makes difficult the regeneration of the accessions as well as the maintenance of their genetic variability. Twenty-three accessions of V. arliculata, V. benghalensis, V. cracca, V. ervilia, V. lutea, V. narbonensis, V. pamionica and V. villosa were grown in the field in 1989 and 1990. Some plants were left uncovered outside"cages until fully mature while others were enclosed in cages when the first flower buds appeared. Plowers of the plants placed inside cages were subjected to the following manipulations:· 1) no manipulation (isolated), 2) tripped (tripped), 3) emasculated and artificially cross-pollinated (crossed}, and 4) emasculated (emasculated). Ten to 180 flowers of each accession in each of 2 replications were subjected to these treatments. V. articulata, V. benghaetsis, V. lutea, and V. ervilia were deemed to be self-pollinated. V. pannocmica was found to be self-pollinated but the high fruit setting of tripped flowers indicated that it would greatly benefit from pollinators. V. villosa was cross-pollinated and required pollinating insects to set fruits and seeds. The other species were not adapted to the field conditions and died.
