A method for distributing families in a progeny test, for improving jack pine and increasing seed production


, : A method for distributing families in a progeny test, for improving jack pine and increasing seed production. Memoire, Service de la Recherche Forestiere, Quebec (65): xiii + 45

The jack pine improvement programme begun in 1979 in NE Quebec is outlined, and a computerized method described for distributing provenances so that, following selection, the distribution of the remaining best 300-500 non-related families allows free pollination and a good seed harvest.
