Surveys the progress of 12 open-pollinated progeny studies from 1950 to 1959. In 1957, preliminary analyses were made of all studies, and complete analyses of two (further data added in 1959). Characteristics studied were: (1) crown width, (2) height, (3) d.b.h., (4) resistance to Cronartium fusiforme, (5) stem crookedness and forking, and (6) natural-pruning height. Heritability values computed for (1), (2), (3) and (6) showed these characteristics to be strongly inherited.
