The study on the breeding system of Grewia optiva has been carried out to observe the different aspects of floral biology and to test for the presence or absence of self-incompatibility. Compatibilities were inferred on the basis of difference in fruit-set between self and cross-pollinated flowers together with the examination of pollen on the stigmas. The species is predominantly cross-poilinated.
