Download or read book Use of Molecular Markers for Detecting and Identifying Acacia Hybrids for Commercial Plantations written by R. Wickneswari and published by . This book was released on 1996 with total page 6 pages. Available in PDF, EPUB and Kindle. Book excerpt: Interspecific hybrids and parental genotypes of Acacia mangium and A. auriculiformis can be distinguished using the isozyme marker,Gdh-I. A, mangium yielded 22, 23 and 33 genotypes at Gdh-I whereas A.auriculiformis yielded only 11 genotype at Gdh-I. Hybrids betweenthe two species can be identified as 12 or 13 genotypes at Gdh-I. So far only 12 Gdh-I hybrids have been detected. The gene for Gdh-I was expressed in callus tissues, seed leaves, juvenile bipinnate leaves, mature phyllodes and inner bark tissues which allows identification of hybrids at any development stage.
