Abstract
A field experiment was conducted during Rabi season of 2014-15 to study “Evaluation of Genetic Variability and Varietal Performance of Gladiolus (Gladiolus hybridusHort.)” at the Instructional Farm, Department of Floriculture & Landscaping, College of Horticulture & Forestry, Jhalarapatan, Jhalawar. The experiment consisted of 12 varieties „African Star‟, „Arti‟, „Darshan‟, „Friendship‟, „Hunting Song‟, „Legend‟, „Pusa Srijana‟,„Pusa Kiran‟, „Snow Princess‟, „Sunayana‟, „Trader Horn‟ and „Urmi‟ laid out in randomized block design with three replications.
The variety „Trader Horn‟ was found superior for number of leaves per plant (9.75), plant height (137.09 cm), spike length (123.38 cm), floret diameter (10.93 cm), duration of flowering (16.17 days), number of florets per spike (20.08) and number of cormels per plant (70.83). The „Legend‟ was noted best yielding variety in respect to, maximum number of spikes (37.0) per plot, number of corms per plant (2.50), number of corms per plot (37.67), sprouts per corm (2.67) and B:C ratio(2.18). The maximum vase life was observed in „Darshan‟ (17.56 days) and maximum number of florets remaining open at a time in vase was observed in „Hunting Song‟ (6.78 florets).
These characters may be considered by breeder for breeding program. High heritability with high values of genetic advance was observed for weight of cormels / plant, number of cormels / plant, rachis length, spike length, weight of corm and number of spikes / plot.
Spike length had high positive association with rachis length, floret diameter, spike diameter, duration of flowering, number of florets / spike, number of cormels / plant, diameter of corm, weight of corm, weight of cormels / plant, size index of corms and number of florets remain open at a time in vase.
