Sporad Formation And Pollen Fertility Of Nine Local Coconut Cultivars
Tessie C. Nuñez
Abstract:
Sporad formation and pollen fertility were studied in nine local coconut cultivars. Varying frequencies of abnormal sporads such as dyads triads pentads, hexad and heptads were observed. Normal sporads (tetrads) occurred highest m Lingkuranay (99%) and lowest in Coconino (58%). Pollen fertility rang d from 66% (Coconino) to 96% (Baybay Tall). Significant positive correlation (r = 0.75) was seen between tetrad frequency and pollen fertility percentage.
