The designation P 1740 is not a separate variety, but rather an identifier for a clone or line of the Williams variety used in comparative trials studying the influence of various rootstocks on fruit crop productivity.
The literature lacks specific descriptions of morphological traits or unique agrotechnical characteristics for this clone that would distinguish it from the base Williams variety. In scientific publications, the number appears exclusively in the context of yield assessment on various types of rootstocks.
