Characterization and assessment of genotypic variability in plant morphological characters of guava

Abstract

The present investigation was undertaken to characterize and evaluate the morphological diversity among 27 guava (Psidium guajava L.) genotypes along with one check variety (L-49) under agro-climatic conditions of Akola. The study focused on assessing plant morphological traits such as plant height, canopy spread (N-S and E-W), stem girth, and branching pattern through single replicated observations. Significant variability was recorded across genotypes, with plant height ranging from 1.58 m (L-49) to 2.53 m (AKG-37), and stem girth varying between 25.5 cm (AKG-15) to 40.1 cm (AKG-5). Branching patterns were categorized as spreading, erect, or dropping, highlighting distinct architectural growth habits among genotypes. The variation observed in canopy structure and stem girth reflects the genetic diversity present in the guava germplasm, offering potential for selection and improvement in future breeding programs. These findings will aid in identifying promising genotypes with superior plant architecture suitable for high-density planting and sustainable orchard management.
