A survey of these elite palms indicated that they are free from disease, although growing in diseased environment for two or more decades. All these elite palms conform to a spherical or hemispherical canopy, the other being the large number of leaves showing a slower rate of senescence, and well-supported (non-buckling) bunches which become ready for harvest at regular intervals. A large number of vegetative and floral characters have been recorded for the inclusion in a model for an ideal plant type in coconut. The seedling progenies raised from the elite palms have been studied using a cumulative indexing procedure and compared with seedling progenies of certain pre-potent palms which show a high rate of yield transmitting ability. Some progenies appeared more uniform than others, thus bearing a close resemblance to those of the prepotent palm. They have been planted both in healthy and disease-affected areas for analysing their further behaviour. Details of above study are discussed in this paper.enArticle
