Genotyping of gene-linkage or gene-target markers was the most crucial part of predicting (or diagnosing) whether desired genes exist in germplasm and progenies in crop molecular breeding procedure such as MAS (marker-assisted selection).It has become a major bottleneck that preparation of sufficient quantity and good quality genomic DNA from various tissues of large number of samples of breeding population in rice.A variety of DNA preparation methods and commercial kits are available.However,they are either time-consuming,low throughput,low yield,or costly.The other,emerging analytical system such as HRM,T-ARMS-PCR and KASPTM which were based on SNP (single nucleotide polymorphism) had been applied increasingly,besides SSR and InDel analyses.These necessitate the development of a universal,more efficient and labor-saving protocol for isolating compatible gDNA from rice plants,and being applied to molecular breeding.

巴西橡胶树(Hevea brasiliensis)是一种重要的产胶植物和经济作物。国内外研究者先后从橡胶树cDNA文库或其总基因组中克隆获得了近420种基因或cDNA,不仅工作量大而且无法确定其在橡胶树染色体上的位置和分布特点。利用分子标记技术构建的橡胶树连锁遗传图饱和度也不够,许多功能基因在染色体组上的连锁关系和位置都不清楚,直接应用橡胶树育种难度较大。而从单染色体或染色体片段入手,再进行体外P

农作物遗传资源是生物多样性的重要组成部分，也是粮食安全的重要保障。但是，由于新品种的大面积推广，导致品种单一化和遗传多样性丢失严重。为了保护这些珍贵的遗传资源，世界范围内大多通过种质库等异地保存方式保护传统农作物品种资源。然而，异地保存不能保持农作物遗传资源在原有环境中的动态进化过程，丧失了农民选择和管理发生遗传变异的机会，导致遗传多样性的丰富度降低，甚至不能适应新的生态环境和抵抗新产生的病虫害。
