Studies on Physical Attributes of Guava (Psidium guajava L.) Genotypes in Awadh Region

Abstract

Guava (Psidium guajava L.), a prominent fruit in tropical and subtropical regions, exhibits significant variability in physical attributes across different genotypes. This study aimed to evaluate the physical characteristics of eight guava genotypes (Lalit, Shweta, CISHG-1, CISHG-31, Allahabad Safeda, L-49, Taiwan, and VNR Bihi) in the Awadh region. The attributes assessed included fruit length, breadth, weight, volume, and specific gravity. Results indicated substantial variations among the genotypes. The longest fruits were observed in Taiwan (9.88 cm), while Shweta had the shortest (6.17 cm). Taiwan also exhibited the greatest breadth (9.29 cm) and weight (465 g), whereas L-49 had the smallest breadth (6.24 cm) and weight (141 g). Fruit volume ranged from 139 ml in L-49 to 462 ml in Taiwan. Specific gravity varied from 1.005% in VNR Bihi to 1.030% in Shweta, indicating differences in fruit density. These findings highlight the genetic diversity among guava genotypes and underscore the potential for selecting specific genotypes based on desired physical attributes for cultivation and market preferences. This study provides valuable insights into guava breeding programs aimed at improving fruit quality and marketability.
