Abstract
The length of the juvenile period was recorded for 7 616 pear seedlings planted from 1962 through 1966 at Beltsville, Maryland.
The mean juvenile period varied by planting year from 4.2 to 5.9 years.
Length of the juvenile period was affected by planting method and selection of parents transmitting precocious flowering.
Stem diameter was not a reliable predictor for length of juvenile period in pear seedlings since these two variables were not significantly correlated for all planting years, progenies, or parents.
Thus stem diameter cannot be used for preselecting seedlings with a short juvenile period.
