Abstract: An investigation was carried out to study their performance of gladiolus cultivars under Nilgiris conditions. It also aims to study the genetic variability and correlation of the different morphological characters influencing the flower yield in different genotypes of gladiolus. The experimental material comprised of twelve varieties viz., Arka Amar, Arka Kesar, Arka Swarna, Arka Shobha, Arka Sapna, Aarthi, Poonam, KumKum, Pusa Sagun, Dharshan, Arka Gold and Arka Sagar were evaluated in Randomized Block Design with three replications during Kharif 2016-2017 at Horticultural Research station, Tamil Nadu Agricultural University, Ooty. The observations were recorded on plant height, days to sprouting of corms, leaf width, number of leaves per plant, days to emergence of spike, days to flowering, rachis length, number of spikes per plant, vase life in water, number of corms per plant, weight of single corm, diameter of corm, number of cormels per plant, weiht of single cormel and diameter of cormel. From the present investigation, it can be concluded that among the genotypes Poornima and Kamini recorded maximum flower yield and number of flowers per plant. Path co-efficient analysis showed that rachis length, diameter of cormel, number of corms per plant, number of florets pr spike and weight of cormel may be considered for further improvement. However, Floret length and floret breadth may also be considered as a criterion for selection.
