本文评论了有关椰子育种的试验和理论研究,并提出了提高椰干产量的途径。扼要地讨论了花的生物学,证明高种椰子是异花授粉的。对母树选择的可能性作了评价;但试验的证据指出,这种技术是无效的,这可能是由于椰子产量遗传力低所致。苗圃选苗能提高产量,但这种改进并不是遗传性的。应该鉴定地理变种的可能价值。认为后代鉴定是发现优势植株的最可靠方法,并讨论了利用这种植株的方法。关于杂交种种子的可能价值需要进行准确的鉴定。 This paper reviews experimental and theoretical studies of coconut breeding and suggests ways to increase copra production. The biology of flowers is briefly discussed, demonstrating that cross-pollinated coconuts are cross-pollinated. The possibility of mother tree selection was evaluated; however, the experimental evidence indicates that this technique is ineffective, possibly due to the low heritability of coconut production. Nursery seedlings can increase production, but this improvement is not hereditary. The possible value of a geographical variant should be identified. Identification of progeny as the most reliable method of identifying dominant plants is considered and methods of utilizing such plants are discussed. The potential value of hybrid seeds needs accurate identification.
