Heritability Construction for Provenance and Family Selection

Concepts and procedures for heritability estimations through the variance components and the unified F-statistics approach are described. The variance components approach is illustrated by five possible family selection schemes within a diallel mating test, while the unified F-statistics approach is demonstrated by a geographic variation study. In a balance design, the use of the heritability formula h2 = 1-(1/F) is recommended. The F value is the same computed F value used in the analysis of variance for testing quality of genetic units.
