Online published on 21 March, 2016. Abstract The study was undertaken to explore the variability for agro-morphological and phyto-chemical traits in the Indian Aloe [Aloe vera (L.) Burm. f.] germplasm at National Bureau of Plant Genetic Resources, New Delhi, during 2009–10. Several explorations were made in diversity-rich areas to collect the germplasm. Fifty diverse genotypes were collected from the 13 states in the country. These accessions were planted and studied for variability analysis for agro-morphological and phyto-chemical parameters. Significant differences were observed for both the traits, indicating a tremendous variability in Aloe germplasm. The highest estimate of genetic combining variability (GCV) was observed for fresh weight per plant (28.07%), followed by gel content (25.82%) and aloin content (18.81%), while highest heritability was recorded for fresh weight per plant (98.20%). High broad sense heritability along with high genetic advance and high genetic advance as per cent of mean was estimated for fresh weight per plant. The genotypes, IC11251, IC471883, IC112531, IC422483 and IC265889, were found superior with respect to yield and quality characters.
