Abstract
Although guava plants were domesticated over 2000 years ago, their commercial cultivation was not reported until 1526. Since then, significant achievements have been made in the breeding of guava, and in India, work on guava improvement began for the first time in 1907. Achievements in guava breeding have significantly helped to increase the profitability of guava cultivation and have been a subject of research for several decades. Breeding programs have been successful worldwide to develop guava cultivars with improved yield and enhanced disease resistance and fruit quality. In the future, the development of genetic linkage maps, tools like marker-assisted selection (MAS), clonal fingerprinting, genome sequencing, transcriptomics, genome-wide association studies, genetic diversity analysis, etc. will facilitate crop improvement approaches in the guava.
