Characteristics and variability of half-sib progeny as the base for ginkgo breeding
The analysis of several morphological traits and phenotypic characteristics of ginkgo seedlings in juvenile tests with half-sib lines in two successive years provide the bases for further planting stock breeding and production for the purposes of urban coenoses and for the establishment of target plantations of this species. The comparative analysis enables the identification of planting stock for further breeding programmes with the aim of getting new ginkgo varieties. Thus, the justification for the protection of the researched ginkgo genotypes and the need for their multiplication were confirmed.
Key words: Ginkgo biloba L., adaptation, age, selection.
