Conservation, Exploitation And Use Of The Ginger Family (Zingiberaceae) At The National Genebank In Vietnam

There are 741 accessions in the ginger family such as turmeric, ginger, galangal, and pinecone ginger collections conserved at Plant Resources Center, Vietnam. These collections were highly diverse in the number of accessions and species composition. The results of the Zingiberaceae exploitation shown the G10 ginger variety plants reached around 63.7 - 77.5 cm in height, 400 - 500 g/clumps in fresh weight, 25 - 27 tonnes/ha in fresh yield. The G10 ginger variety contained 4.37% oil, 1.2 mg/kg Zn and 9.31 mg/100g Vitamin C. This G10 ginger variety resistance to leaf spot and green aphids. In addition, the N8 turmeric variety plants reached 130 - 170 cm in height; 880 - 1000 g/clumps in fresh weight and 35 tonnes/ha in yield, curcumin content 6.2 - 6.6%, essential oil contents 2.5 - 2.7%. This turmeric resistance to heat stress, leaf spot, and green aphids. The conserved root and tuber crops at PRC are very diverse both of the amount of sample in collections and species. Conservation and evaluation on root and tuber crops reviewed the promising G10 ginger and N8 turmeric varieties had high yield, good oil content to release for production
