Breeder's methods for selecting good mother palms

In construction

For Tall-type varieties, one of the main challenge is to find seednuts conceived by selfing, because of inbreeding depression.

The production of inflorescences and bunches in not regular during the year.
It may have a season where you often see two young inflorescences open in the same coconut; this season is not the good one for haversting seednuts.

If the coconut plantation is constituted by a very special variety, which is rare or not found in other places, it is avised to maintain and breed this special variety.
If the plantation is constituted by a variety wich is rater common, shared by many farmers around the village ot within the country, diversifying seed sources is advised. In the past, some polynesian farmers may have harvest many coconut seednuts in the same palms and plant close together; so very probably, in some plantations, palms planted close together are half or full sibs. Thus, to avoid inbreeding depression (crosses beween half or full sibs), when planting a new field, it is advised to get the seednuts from different locations, such as different coconut plantations or different places within the same plantation. Coconut exchanges between farmers are strongly advised and should increase.
If existing in the plantation, rare forms, such as Sweet husk or pia (tender meat) should be conserved and multiplicated. Even if these few palms do not have yet a high commercial value, they are important for the future as they may become the most profitable in the market.
