The results showed that both the modified SDS and CTAB methods are better than the original SDS and CTAB methods. Yield of genomic DNA was not only related to extraction methods,but also to cotton tissues.

• 本文以多酚类植物棉花为研究材料,对SDS法、CTAB法、改良SDS法和改良CTAB法进行了比较研究,结果表明:改进的SDS法和改进的CTAB法分别优于原SDS法和原CTAB法,两种改进的方法对提取棉花基因组DNA有异曲同工之妙。
