【Abstract】 Crop germplasm resources is the basis of crop breeding,genetic research and ecological stability,and it is considered as the national strategic resources for its importance in food security and agricultural sustainable development. The third national census and collection of crop germplasm resources Hubei project team collected 118 samples of crop germplasm resources from 12 villages in5 townships of Lichuan city,consisting of 56 food crops,50 vegetables,7 economic plants,and 5 fruits which belonged to 42 species of 35 genera in 20 families. In this study,the planting area and the growth and decline conditions of crop germplasm resources were analyzed. Furthermore,The conservation and exploitation of local germplasms were subsequently discussed based on current status.更多还原
