Heritability and combined parental information to define the number of crosses in circulant diallels

Abstract: In many agricultural crops, the number of parents used in cross breeding make it difficult to obtain all possible hybrids diallels. Therefore, using maize as a model plant and based on traits with high low heritabilities, aim present study was quantify correlation estimates general combining ability (GCA) specific (SCA) between complete diallel circulant diallel, without inclusion parents. For heritability trait, GCA can be obtained s values, whereas for SCA estimates, values close half should used. information from must estimates. considering stabilization r above 0.70 s=7, greater than models.
