Aim of this research was to explore genotypic and phenotypic variability, heritability and genetic advance of progenies derived from hybridization of <em>Vanda</em> ‘Adrienne’ × <em>Ascocenda</em> ‘Peggy Foo’ with <em>Vanda</em> <em>malinii</em> × <em>Vanda denisoniana</em> Benson &amp; Rchb.f, and to find best characters used for selection. The experiment was conducted at Segunung Experimental Garden of Indonesian Ornamental Crop Research Institute (IOCRI) on altitude of 1100 m above sea level from June 2013 until December 2016. Thirteen genotypes derived from hybridization of <em>V.</em> ‘Adrienne’ × <em>A.</em> ‘Peggy Foo’ with <em>V.</em> <em>malinii</em> × <em>V. denisoniana</em> of 1A, 2A, 21A, 27A, 50A, 52A, 98A, 101A, 102A, 113A, 116A, 120A, and 120B were used in the study. The experiment was arranged in a Randomized Complete Block Design (RCBD) with three replications. Results of the study indicated that range of genetic variability was varied from 1.2-184.7% with wide genetic variability determined on number of leaves per plant (NLP) up to 26.5% with 184.7% for leaf width (LW) and 24.7% for spike length (SL). Moderate heritability of 25.2% for NLP, 21.0% for LW and 25.2% for SL coupled with high genetic advance percent of mean up to 59.7% for NLP, 939.7% for LW and 33% for SL, reflecting the presence and expression of additive gene action of these traits. The results indicated the importance of these three characters best used as selection criteria for Vanda genotypes.</p> ER -
