HYBRIDIZATIONS BETWEEN SELECTED ANNONACEAE SPECIES

The studies conducted in Serdang , Selangor, Malaysia, involved six selected species of Annonaceae, namely: Annona muricata, A. squamosa, A. glabra, A. montana, A. rollinia, and A. reticulata. Hybridizations were attempted between all species and also their reciprocal crosses. Although fruit was formed between some species, seeds were not viable except for those produced in two hybridizations: Annona muricata (female) x Annona montana (male) and Rollinia mucosa (female) x Annona muricata (male). The former F1 hybrids produced plants that flowered but set no fruit. The latter F1 hybrids produced fruit similar to Rollinia.
