Abstract

Sporad formation and pollen fertility were studied in nine local coconut cultivars. Varying frequencies of abnormal sporads such as dyads, triads, pentads, hexads and heptads were observed. Normal sporads (tetrads) occurred highest in Lingkuranay (99%) and lowest in Coconiño (58%). Pollen fertility ranged from 66% (Coconiño) to 96% (Baybay Tall). Significant positive correlation (r=0.75) was seen between tetrad frequency and pollen fertility percentage.
