in viticulture, a clone is single vine that has been selected from a "mother vine" to which it is identical. this clone may have been selected deliberately from a grapevine that has demonstrated desirable traits (good yields, grape disease resistance, small berry size, etc.) and propagated as cuttings from that mother vine. varieties such as sangiovese and pinot noir are well known to have a variety of clones. while there may be slight mutations to differentiate the various clones, all clones are considered genetically part of the same variety (i.e. sangiovese or pinot noir).
