Quality germplasm, in this case seed, is the most significant input in farming systems, including agroforestry systems. Quality seed determines the upper limit of yield, the ultimate productivity of other inputs, transference of genetic information from one generation of crops to another, the basis of economic yield of the majority of crops and makessubstantial contribution to productivity independent of other inputs (Sperling et al. 1996; Simons 1996; Cromwell et al. l993; Cromwell 1990; Thomas 1990). It is, therefore, an important source of innovation and intervention, particularly for farmers with small holdings of marginallands, who have low capacity to absorb high losses and less resources for alternative inputs (Simons et al. 1994; Cromwell et al. 1993).
