The timing and patterns of initiation and differentiation of strobili on three clones of loblolly pine located in Washington, N.C., were similar, although the cone‐producing abilities of these clones were significantly different over a 5‐yr period. Male strobili were initiated in early July and were differentiated by mid‐September. Female strobili were initiated about the last week in August and were fully differentiated by mid‐November. There were significant differences in the developmental patterns of the long shoots on these three clones.
