AKASI, Takateru, YOSHlMARU, Hiroshi and MASUDA, Masami : A method to estimate heritability from the data of line plantings of strains with no replications. J. Jpn. For. Soc. 75 : 70〜72,1993 A narrow sense of the heritability of several character of forest trees are obtained through analyses of the data from extensively planned and well-maintained progeny test plantations. However, forest trees have relatively long developmental times and require many years before data collection can be started. Therefore, if a broad sense heritability can be evaluated from the data of clone collection gardens which are set up in an early step of breeding projects, it will provide useful information for further planning. Although clone collection gardens usually have no replications which are necessary for analysis-of-variance methods to calculate heritability, we developed a simple method using covariance to estimate a broad sense heritability from such data. This method can be applied also to data from family (half sibs, full sibs, and so forth) collection gardens with no replications to estimate a narrow sense heritability.
