The entirety of the external appearance of an organism whose individual characteristics can be visually described and categorised. The term "phen" means an emerging (hereditary) trait of an organism that forms the phenotype together with other traits. The phenotype of a vine variety thus contains a catalogue of characteristic expressions which can be used to visually distinguish and characterise a variety from another variety. In the case of the vine, these include berry colour and shape or the shape and hairiness of the leaves (but they can also be other, visually unrecognisable characteristics such as the time of ripening). The different Pinot varieties are different phenotypes of a genotypically identical grape variety. However, they are considered to be independent varieties. In contrast, a genotype represents a specific genetic information pattern within the DNA chain. See also molecular genetics and heterozygosity.
The wein.plus encyclopaedia is a comprehensive, well-researched reference work. Available anytime and anywhere, it has become an indispensable part of teaching, used by students and myself alike. Highly recommended!Dominik Trick
