|Abstract: ||To make operational on-farm crop genetic conservation strategy in Ethiopia, we have to
understand the factors that determine farmers’ for managing portfolios of crop varieties.
Identifying farmers’ derived demand for sorghum varieties and drawing policy implication for
on-farm genetic resource conservation in Ethiopia is the main objective of this paper.
Farmers’ preferences for varieties conditioned on different preference parameters are the
theoretical basis for this study. Count index and Shannon index are used to measure the onfarm
sorghum genetic diversity of the studied area. Poisson and Tobit regression models are
estimated using a rural household survey data collected from 205 households in Tehuledere
Woreda, Amhara National Regional State of Ethiopia.
The findings of empirical estimation shows that family size of the household, land
characteristics, concern factors, number of oxen ownership and access to cash crops are
promoting factors for variety richness of sorghum genetic diversity in farm household. On the
contrary, the most important factors detaching the link between farmers survival strategy and
sorghum genetic diversity are access to extension services, experience on using improved
varieties, access to road infrastructure and access to market services. The results imply that
on-farm crop genetic resource conservation will be negatively correlated to the over-all
agricultural development in a specific region. Therefore, there is a need for flexible incentive
structures to maintain CGRs diversity at a social optimum and to off-set the negative effect of
