https://doi.org/10.1007/978-3-322-84002-8tandard methods and techniques of conservation and regeneration of gene resources are discussed in relation to the objectives of conservation, and elementary consequences for declaration are drawn. The need for research centered on the field of gene conservation is emphasized, and the significance of legislation in this concern is addressed.

It is demonstrated that simple random sampling is not an appropriate method since, as a rule, genetic types cannot be assumed to be

Martin Aigner,Günter M. Zieglerg the latter, isoenzymes are preferentially regarded as traits whose variability is attributable to environmental rather than to genetic differences. Their interest is thus focussed on finding correlations between isoenzymes and environmental variables. The existence of such correlations was demonst
