Abstract : Upon conducting a biodiversity survey in Yuk Yu, Rkap and Jara Villages, Nam Nung Commune, Krongno District, Daklak Province in Vietnam, the results showed that variety network and variety preservation methods in Nam Nung Commune have not been much affected by market and economic changes, especially in Ja Ra Village. The crop diversity is different among villages and among groups of households in a village. Some crops came to Nam Nung from the Daklak Center for Agricultural Extension and socioeconomic development programmes of the local Government. On the positive side, these crops have diversified the crop structure in Nam Nung. Five new fruit trees imported into Nam Nung by the Program for Reclaiming Intercropped Gardens of the Daklak Center for Agricultural Extension are mango, rambutan, custard apple, durian and jackfruit. The 135 Program for Particularly Difficult Communes of the Government provides hybrid seeds of maize varieties (LVN 10 and DK88) and high-yield beans (green bean, soyabean, groundnut, black bean and red bean). Cash crops from new crop models of the Daklak Center for Agricultural Extension and other development programmes are coffee, pepper and cashew nut. In general, groups of poor households conserve more crop diversity than the average and rich ones while the rich groups tend to accept new crops to replace the traditional ones. As they have more resources, they can invest in growing new crops to gain better economic efficiency. The adoption of new crops is the main cause of genetic erosion of local traditional germplasm. This is an important issue, which needs to be addressed in the in situ crop diversity conservation on-farm in Daklak.
