Extent and Pattern of Seed Setting in Faba Bean under Self and Open Pollination Arrangement and its Influence on Seed Production

Faba bean performance under self pollinated plot over open pollinated

Abstract

Faba bean ischeapest sources of protein and other nutrients including minerals, cool season legume
crop. To know the magnitude of cross-pollination, an experiment was conducted with seven
genotypes, under control/self and open-pollinated condition at ICAR Research Complex for
Eastern Region Patna during cool seasons 2016-17. Experiments on faba bean are being regularly
conducting since thecool season of 2007-08. Results revealed that seed yield and yield attributing
traits has been reduced under thecontrolled/self-pollinating condition as compare to open/cross-
pollinated condition, though the reduction was not same for all tested genotypes. The magnitude
of yield reduction was in the range of 13.3 to 41.7 percent. Harvest Index was also gets diminished
from maximum 49.2 to 21.7% with reduction of minimum 37.8 % to maximum 50.7%. It was also
observed that honey bee (Apis mellifera) was the major pollinator bee. Results clearly indicate that
apoides play a decisive role in therealization of potential yield by the cross-pollination mechanism
of allogames faba bean.
