Abstract

Four extraction methods and sample types were evaluated for yield, quality and suitability of genomic DNA for ISSR marker amplification in teak (Tectona grandis). Both CTAB and SDS based extraction procedures extracted better quantity and purity index of genomic DNA. Leaves of trees, bud grafts and
seedlings yielded better DNA than seeds. Using identical PCR conditions, DNA extraction methods and sample types influenced amplifications of ISSR markers, with no amplifications among seed samples. DNA extraction method and sample type are very important consideration for reproducible ISSR-based molecular marker analysis in teak
