Potato improvement through parental line breeding—A five year report of the North Central 35 Regional Project, NC-35

The NC-35 project has established a unified program designed to develop parents improved genetically for certain important economic characters. Researches have been conducted emphasizing concentration of genes conditioning desired characters, inheritance studies, incorporation of desired characters from IR-1 stocks, and improvement of breeding and testing methods. Though the work is difficult, progress has been made. Twenty-three publications have been reported resulting from researches relating directly or indirectly to the NC-35 project. It is anticipated that more rapid progress will be realized as the use of haploid and other new materials develop.
