Makapuno is the most popular and economically important among the soft-endospermed coconut (Cocos nucifera L.). In 1996, makapuno export was valued at 2.5 M USD. Both local and export markets are expanding but supply fell short by about 4 M kg. In nature, makapuno is found only among the Laguna tall populations. As tall, embryo cultured homozygous makapuno palms (mm) from these heterozygous makapuno-bearing sources are late bearers and highly cross pollinated. At NCRC-V [National coconut Research Center-Visayas], four dwarf x makapuno crosses were developed namely CNO x MAC, MRD x MAC, MYD x MAC and TAC x MAC. Homozygous makapuno (mm) palms of the second and third filial generations have been derived from those hybrids. The homozygous palms proved to be precocious, flowering at 26 months from planting. Self pollination and makapuno yield percentages are also high
