Many species of Cuphea genus show promise as rich natural sources of valuable seed oils for commercial utility.Among them are C.lancelota and C.viscosissima which seed oils contain mediumm-chain fatty acids.Recoprocal crosses were made between species to assess their usefulnes for Cuphea breeding programme.The degree of crossability between C.lanceolata and C.viscosissima was determinated by pollen grain germinatin and pollen tube growth observed using fluorescence microscopy in addition to capsule formation and seed number per capsule.Treatment of the pollen grain with a laser microbeam reduced the number of germinated pollen grains, tubes growth in the pistil and seed set when C viscisissima plants were used in the crosses as a female form.In the cross C.lanceolata (female form) x C viscosissima the pollen treatment with a laser microbeam improved pollen tube growth but reduced seed set.Crossability evaluated on the basis of pollen tube growth and seed set showed unilateral intraspecific incompatibility in crosses involving C.lanceolata plants as a female form.
