Abstract: India is bestowed with several agro-climatic zones conducive for production of sensitive and delicate floriculture products. Ornamental flower seed production seems one of the viable options to explore with great export potential and the Indian climatic conditions are favorable for their cultivation. West Bengal has good environment during winter which is highly suitable for flower seed production. With the above consideration, the present investigation has been undertaken to evaluate of ten flower crops such as Candytuft, Flox, Dimorphotheca, Saponaria, Dianthus, Cornflower, Annual chrysanthemum, Scorodynum, Lupin and Poppy and document there various seed quality parameters during 2014-2015 at Mondouri farm, BCKV, West Bengal, India. Among the winter annuals Saponaria scored highest seed yield per plant (9.63g). Lowest seed yield per plant was recorded in poppy (1.50g). Regarding test weight, lupin recorded the highest performance i.e. 13.67 g followed by dimorphotheca (12.11g), while Poppy recorded the least weight in all situations. Immediately after harvesting among the winter annuals Cornflower was highest germination percentage (90%) and no germination was found in annual Chrysanthemum and poppy. After viability test it can be confirmed that Chrysanthemum and poppy have the dormancy. Both Annual Chrysanthemum and Poppy dormancy period is two months, confirmed it after TZ test. Five months after harvesting highest germination percentage was found in cornflower (72.667), lowest was found in Saponaria and Lupin (64.667). The significant variation among the flower crops for the trait germination percentage.
