Abstract
There has been some inconsistencies in pollination requirement of Brassica juncea which is considered to be self-compatible and to set seeds well without insect pollinators (FREE and SPENCER-BOOTH 1963) and also with insect pollinators in isolation cages (NAMAI 1983 b). In this paper, we reported the relationships among the number of insect pollinators, the number of pollen grains deposited on the stigma and seed set percentage in caged B.juncea (L) Coss., digenomic (AABB), self-compatible and self-fertilizing species, in comparison with B.campestris, monogenomic (AA), self-incompatible and outcrossing species.
