Total height, d.b.h., number of crooks per foot, degree of crook, and crown width ratio were studied in comparing progenies front two seed-production areas against progenies from randomly selected trees in adjacent stands. At five years of age, progenies from seed-production area trees had fewer crooks than progenies from the adjacent stand trees; however, no significant differences were found in any of the other traits studied.
