Stability Of The Nut Characters Of Different Coconut Cultivars

Abstract:

Nut size, weight of nut components, meat thickness, copra yield per nut and oil content of eleven coconut cultivars were observed to be stable during the five-year evaluation period. Except for the more variable weights of water and husk, coefficient of variation of their yearly means were most often below 10%.
