It is a native plant of South and Southeast Asia and is distributed in warm temperate, tropical and subtropical countries of the world. But more number of species is found in the regions of India, Malaysia and China (Anon., 1959). The attractive foliage and fragrant white flowers make it a highly valued commercial crop in India, Central Asia, Afghanistan, Iran, Nepal, Thailand, China, Sri Lanka and the Philippines for its fresh flowers. Commercial cultivation is confined to three species, viz., Jasminum sambac, Jasminum auriculatum and Jasminum grandiflorum (Green and Miller, 2009). In India it is mostly cultivated in South India. Jasmine flowers are exported to countries like Singapore, Malaysia, Japan, UK, USA, UAE International Journal of Current Microbiology and Applied Sciences ISSN: 2319-7706 Volume 6 Number 12 (2017) pp. 40-44 Journal homepage: http://www.ijcmas.com Assessment of crop performance and its related physiological parameters are important for commercial cultivation as well as crop improvement programme point of view. The unique white fragrant flowering crop jasmine is a highly valued ornamental plant for home gardens and commercial cultivation in many warm temperate, tropical and subtropical countries of the world. Although many varieties of Jasminum species are cultivated in Tamil Nadu as well as in India, but Ramanathapuram Gundumalli, Madanban, Ramabanam, Single Mohra, CO.1 Mullai, Parimullai and CO.1 Pitchi are largely cultivated. There is less or no scientific evidence available on crop performance during lean flowering season. Highest plant height, plant spread, number of branches and flower bud yield per plant were recorded in CO. 1 Pitchi. All the vegetative and yield parameters had direct correlation with the total chlorophyll content and relative water content. Highest total chlorophyll content (1.538 mg g -1 ) and relative water content (86.50%) were recorded in CO. 1 Pitchi. It is important to study the qualitative and quantitative flower quality parameters to maintain the uninterrupted supply chain during lean flowering period.
