Abstract

Seven genotypes of blanket flower were collected from Southern parts of Rajasthan through single plant selection sampling method. These were evaluated with respect to morphometric traits, floral yield attributes and flower shelf-life under ambient conditions for further utilization in crop improvement programmes to meet the future demand of floricultural industry. After screening seven genotypes of the open-pollinated seedlings of blanket flower maintained in the field repository, two lines i.e., MPUAT GOPS-1 and MPUAT GOPS-3 were identified as most promising. MPUAT GOPS-1 has compact double fl owers with yellow ray fl orets and fl ower yield ranges from 154.0 to 351.0 g/plant and obtained fl ower yield from 17.11 to 38.99 t/ha, mostly preferred by farmers. However, MPUAT GOPS-3 is a compact double flower with dark red ray florets and flower yield ranges from 174.6 to 328.0 g/plant and obtained flower yield from 19.39 to 36.44 t/ha. Further, MPUAT GOPS-5 and 7 are also promising with respect to flower yield and quality attributes.
