Thesis. 81p.https://krishikosh.egranth.ac.in/handle/1/5810170269The present experiment was conducted at Instructional Farm, College of Horticulture, BUA&T, Banda during November 2019 – April 2020 with fifteen varieties of gladiolus (Gladiolus hybridus Hort.). The experiment was laid out in Randomized Block Design (RBD) with three replications. The observations were recorded for various vegetative, flowering and corm parameters. The analysis of variance revealed wide and significant variations for most of the characters. The variety Praha took minimum days to sprouting of corm (5.17 days). Minimum days to spike emergence (66.67 days) and opening of first floret (86.21 days) were recorded in variety Gunjan. Among the varieties studied, highest plant height was observed in variety Shabnam (105.47 cm), whereas maximum spike length (89.93 cm) and rachis length (55.64 cm) was recorded in Essley Blue. Maximum floret size was recorded in variety Essley Blue (9.82 cm). Number of florets opened at one time was found maximum in variety Novalux (8.47). Shabnam showed maximum duration of flowering (17.98 days) and number of florets per spike (14.22). Suchitra recorded maximum vase life of 17.33 days. As for as corms and cormels production is concerned, maximum number of corms per plant were found in variety Viola (2.27). Corm diameter (6.77cm) and corm weight (100.00 g) was recorded maximum in the variety Praha. However, number of cormels per plant (41.97) and weight of cormels per plant (13.42g) was found maximum in variety Essley Blue. Days taken to spike emergence exhibited highly significant and positive correlation with days taken to opening of first floret. Duration of flowering showed significant and positive association with number of florets per spike. Plant height exhibited highly significant and positive correlation with spike length and rachis length; significant and positive association with vase life. Spike length exhibited highly significant and positive correlation with rachis length. Rachis length exhibited highly significant and positive correlation with vase life. Corm diameter showed highly significant and positive correlation with corm weight. Overall varieties Suchitra, Viola and Novalux are found suitable for commercial production of cut spikes as well as corms in Bundelkhand region.EnglishThesis
