In a study of Acacia species, the seed parameters of length, width and thickness of 23 genotypes were measured in millimeters. Analyses of the three traits showed significant species differences. The very low error variance component signified that the traits are highly heritable. The high %-contributions combined with the high species coefficient of variation indicated that seed size could be altered by selection and breeding. The strong correlation between seed length and width indicated that improvement in one character would improve the other. The three seed parameters appear to be governed independently and the association between pairs of traits varied considerably.
