Abstract: The variation trendency of crop germplasm resources in Huangpi district of Hubei province was analyzed by using the data of three national surveys on crop germplasm resource in 1956, 1981 and 2014. These three surveys happened during the post-liberation period, the early stage of family contract and the land transfer period. The results showed that 39 landraces which collected from Huangpi district and preserved in the National Germplasm Bank were not planted anymore in 2014. The total planting area of major food crops, major cash crops and major vegetable crops all increased firstly and then declined. While the total planting area of fruit and tea crops was on an upward trend. The planting area of these four kinds of crops was in descending order. The ratioes of the latter to the former were 1/2, 1/10 and 1/10, respectively. The number of crop species and varieties decreased in landrace germplasm resources, but increased in cultivation resources, especially since 1981. Only six landraces （local cowpea, red cowpea, Midiwan radish, Huangzhou radish, Shafan radish and local persimmonra） of three crop species （Vigna unguiculata, Raphanus sativus and Diospyros kaki） were still planted in Huangpi district in 2014. These landraces should be protected and well used in Huangpi district in the future.
