Abstract

The present investigation was carried out to assess the extent of genetic variability, heritability, genetic advance, correlation coefficient and path analysis in 12 gladiolus genotypes, i.e., True Love, Pacifica, Rigency, Yellow Stone, Sagun, Tiger Flame, Praha, Snow Princess, Picardy, Eurovision, Aldebran and Promise. The experiment was laid out in Randomized Block Design with three replications. The row to row and plant to plant spacings were maintained at 30 cm × 25 cm, respectively. From the analysis of data, it can be concluded that the maximum weight of corms per plot was recorded in Rigency followed by Picardy and Tiger Flame. Maximum phenotypic variation was noted for corm weight per plant (180.75) followed by number of days taken full spike emergence (117.18). Positive correlation was recorded corm weight plot with corm size (0.906), spike length (0.764), plant height (0.669).
