Fruit Setting Under Controlled Natural Cross Pollination In Three Populations Of Coconut (<i>Cocos nucifera</i> L.)

Abstract

Four coconut (Cocos nucifera L.) varieties, West African Tall (WAT), Malayan Green Dwarf (MGD), Malayan Yellow Dwarf (MYD) and Malayan Red Dwarf (MRD), planted in the Main Station of the Nigerian Institute for Oil Palm Research (NIFOR) near Benin City, in an isolated seed garden to produce different types of hybrids through open pollination were used Selected dwarf mother palms were emasculated, while the tall mother palms were not, allowing the tall palms to cross pollinate the emasculated dwarf palms. Controlled natural pollination of these selected dwarf mother palms was carried out for four years, 1996 – 2000. Data collected include number of bunches (NOB), number of buttons (NOBT) and number of nuts (NON). The various cross combinations (populations) studied were MGD x WAT (population 1), MYD x WAT (population 2) and MRD x WAT (population 3). Mean squares from the analysis of variance were significant (P Keywords : Controlled natural pollination, Fruit setting percentage Journal of Agriculture, Forestry and the Social Sciences Vol. 4 (2) 2006: pp. 190-195
