This study was taken up as novel attempt toassess the genetic diversity of G. villosa in Kachchh regions of Gujarat, on basis of morphological and pomological characteristics, for developing phenotypic markers. Field surveys conducted in arid region of Kachchh, Gujarat during March to October, 2015-16 and around twenty germplasm of G. villosa as fruits were collected from different habitats. Data on seventeen characters were recorded on its germination, growth and fruit parameters. High coefficient of variation (%) in days to germination (75.5), number of leaves (56.5), petiole length (47.8), germination (46.3), number of branches per plant (43.3) and plant height (42.1) was found. Range of variation for plant height (cm), number of fruits per 100g (NF), 1000-seed weight (TSW) (g) and fruit thickness (mm) were observed with range (16.7 to 73.0, 370 to 620, 114.0 to 268.1 and 9.7 to 12.3) respectively. Range of value of Pearson’s correlation coefficient varies from –0.70 in between stem girth and fruit thickness to 0.86 in between canopy spread N-S and E-W. Cluster analysis revealed the presence of four clusters at coefficient value of Euclidian distance of 6.4 with 1, 1, 2 and 16 genotypes, respectively. PCA analysis revealed the presence of 84.13% variability among G. villosa genotypes through first six most informative components and it also confirmed the clustering pattern obtained through cluster analysis.
