| dc.description.abstract | An experiment was conducted on investigation and identification of elite mutants induced through physical mutagen for floral traits in gladiolus (Gladiolus hybrida L.) at floriculture unit, UAS, GKVK, Bengaluru during the years 2020-2022. The data from two generations revealed that 25 Gy gamma ray dosage had shown maximum variation in most of the vegetative, floral, corm and quality parameters. In M1 generation untreated corms of Arka Pratham (9.13 days) recorded minimum number of days for sprouting, maximum length of spike was observed in Arka Gold corms treated with 25 Gy (120.07 cm), maximum floret diameter was recorded in Arka Gold corms treated with 25 Gy (11.13 cm), maximum number of spikes per corm was recorded in Arka Amar corms treated with 25 Gy (1.80), maximum diameter of the corm was recorded in Arka Gold corms treated with 25 Gy (12.07 cm), maximum vase life of spikes was recorded in Arka Amar corms treated with 25 Gy (10.00 days). In M2 generation untreated corms in Arka Pratham (9.47 days) took minimum number of days for sprouting, , highest length of spike was recorded in Arka Gold corms treated with 25 Gy (120.87 cm), maximum floret diameter was recorded in Arka Gold corms treated with 25 Gy (11.13 cm), more number of spikes per corm was recorded in Arka Amar corms treated with 25 Gy (2.07), more diameter of the corm was recorded in Arka Gold corms treated with 25 Gy (12.60 cm), more vase life of spikes was recorded in Arka Amar corms treated with 25 Gy (10.53 days), more number of abnormal leaves was recorded in Arka Gold corms treated with 55 Gy (4.69). Among three varieties Arka Amar performed better i.e. maximum number of spikes per corm, number of florets per spike and vase life of spikes was recorded. | en_US |
