Abstract
The work up to 1984 of the P. nigra var. corsicana improvement programme established in France in 1971 is reviewed. The aim of the programme is to develop 2 improved varieties for medium and low alt. regions by selection within 2 populations, one composed of phenotypically selected trees from 4 natural Corsican provenances, the other of trees from plantations in central France. A study was made of the genetic data and methodologies used in early selection of seed trees for the seed orchards established in the Lot department. A study was also made of the genetic variation in 5 natural provenances in Corsica.
