Abstract
A field experiment entitled “Genetic variability, correlation and path analysis for
yield and yield attributing characters in aloe (Aloe barbadensis Mill.)” was carried out at
ICAR – DMAPR, Boriavi during 2019-21 using 26 genotypes of aloe in a randomized
complete block design. The objectives of the study were to estimate the genetic
variability, broad sense heritability, inter-character association and the direct and indirect
effects of yield and quality attributing characters through path coefficient analysis. The
result revealed that IC 310618, IC 310623, GUJ 1, NMRM 2 and IC 285629 were
superior lines for gel and aloin yields. Aloin content (%) was recorded highest in IC
310623 (27.07%). Based on variability studies, parameters viz., plant height, leaf weight,
leaf thickness, exudates yield per plant, leaves per plant and leaf breadth could be selected
for increasing yield as they have high heritability coupled with genetic advance.
