Chapter

Abstract

The coconut palm (Cocos nucifera L.) is one of the most extensively cultivated palms with innumerable uses. The aim of this chapter is to acquaint the reader with natural diversity and genetic resources of coconut and how these have been utlized in breeding programmes in India to increase productivity of coconut plantations. This chapter covers the basic facts about coconut botany and cultivation, followed by a review of germplasm resources, their collection, characterization, conservation and documentation, the use of genetic resources for breeding purposes, the varieties and hybrids that have been developed, breeding for specific traits and also future perspectives.
