Result Analysis on Progeny Tests of Horsetail Beefwood Superlor Trees

Abstract: Analysed and evaluated the hereditary predisposition of horsetail beefwood (Casuarina equisetifolia L.) superior trees. The results indicated that phenotypical selection was available in selceting superior trees. The hereditary variations of main growth traits among and within the families were very obvious, and the heritability of diameter breast-high (0.689) was larger than volume (0.565) than tree heigt (0.550). The genetic gains of superior families selected by progeny test on early tree height, diameter breast-high and volume growth were 8.24%, 14.33 and 24.16% respectively. The studies also showed that the preliminary selection of superior families according to the growth traits of each family of 6-7 years old was practicable. The preliminary elimination of bad clones according to the early diameter breast-high growth of the clones in the seed orhcard was feasible.
