Marigold (Tagetes sp.) is one of the commercially exploited flower crops of both tropics and subtropics. The field trial was measured for twelve marigold genotypes in new alluvial zone at Horticulture Research station, Mondouri, B.C.K.V., Mohanpur, Nadia, West Bengal during Rabi season of 2017-18 to 2018-19.The trend in seed deterioration of those marigold genotypes was observed by storing with five treatments in seed testing laboratory, Department of Seed science and Technology, B.C.K.V. After harvesting seeds were stored in different conditions like Aluminium foil (T1), Cloth bag (T2), Polythene packet of 300 gauge (T3), Brown paper packet (T4) and refrigerator (T5) at 8-10 0C. The different seed quality parameters such as root length(cm), shoot length(cm), germination percentage and vigour index were recorded/determined after harvesting and at every three months interval up to twelve months of storage. Seed storage of all the genotypes failed to attain prescribed germination (70%) as per MSCS of Marigold beyond three months after storage irrespective of the storage conditions; hence, different conditions under consideration may not be recommended for storing of Marigold seeds beyond three months.Joint consideration of germination potential and vigour index indicate that seed storage within refrigerator (T5) as well as in 300 gauge polythene packet (T3) may be recommended for all the genotypes studied upto three months for maintenance of its higher quality.
