Abstract:
The present study was conducted at the Department of Floriculture and Landscaping, Tamil Nadu Agricultural University, Coimbatore. The study was conducted with two year old plants grown under open field condition of seven commercial varieties of jasmine, viz., Ramanathapuram Gundumalli, Madanban, Single Mohra and Ramabanam of the species Jasminum sambac, CO.1 Mullai and Parimullai of Jasminum auriculatum and CO.1 Pitchi of Jasminum grandiflorum by adopting all the recommended cultural practices. The statistical design adopted was RBD. Observations were taken during the critical stages of growth and development namely, pre flowering, flowering, peak flowering and lean flowering stages for all the parameters. Significant variations were observed among the varieties for vegetative parameters during the critical stages of growth. Maximum plant height and plant spread was observed during lean flowering stage (Stage IV). Among all the varieties, the highest values for these were recorded in CO.1 Pitchi. Significant variations were observed among the varieties for yield parameters also. The highest estimated annual flower bud yield was recorded in CO.1 Pitchi whereas the highest hundred flower bud weight was found in Madanban during peak flowering stage (Stage III).
