比较了43株高产母树的1190个自然授粉后代和10株高产母树的224个自然授粉后代在发茅后第5个月时的两个生长性状——根颈围和叶数。试验结果表明,只有5株椰树的后代比其他椰树的后代优越。有60%以上的椰树后代的生长性状平均值超过了参试的1414个后代生长性状的总平均值。母树中有3株是稳定高产树,单株年产80多个椰果、年产椰干15公斤以上。这些稳定高产树的后代,在发茅后第5个月时长势都比其他椰苗茁壮。说明这些高产母树向后代传递生长性状的百分率高,可能是具有遗传优势的母树。用源自3株高产树的146个自然授粉子2代(F_2)进行的试验结果表明,遗传优势没有全部传递给自然授粉的第2代。
Two growth traits, root circumspot and leaf number, were compared between the first and second months after germination of 1190 naturally pollinated offspring from 43 high-yielding parent trees and 224 offspring from 10 high-yielding parent trees. Test results show that only 5 coconut descendants superior to other offspring of coco. Over 60% of the coconut offspring had an average of more than the average of the 1414 offspring tested. Three of the mother trees are stable and high-yielding trees, with an annual output of more than 80 coconuts and an annual output of 15 kg of copra. The offspring of these stable, high-yield trees thrive more vigorously than the other coconut seedlings at the fifth month after the weed. This indicates that the high percentage of high-yielding trees that pass on their traits to future generations may be genetically dominant mother trees. The results of the experiments conducted with 146 natural pollinators, 2 generations (F_2), derived from three high-yield trees showed that the genetic predominance was not fully passed on to the second generation of natural pollination.
