木豆（Cajanus cajan）是印度一种重要的自给作物，在印度传统地方品种和改良杂交种同时种植。基因流可能导致这些地方品种及其野生近缘种的遗传侵蚀，而未来转基因品种的转基因逃逸是另一个潜在危害。为了评估这些因素的影响，需要对基因流进行测量。已经开发出一组10个简单序列重复标记，它们在一系列木豆品种中表现出多态性。这些标记的使用也为评估木豆种群内的遗传多样性提供了一个有效的系统。
Pigeonpea (Cajanus cajan) is an important subsistence crop in India where traditional landraces and improved hybrids are grown alongside each other. Gene flow may result in genetic erosion of these landraces and their wild relatives, whilst transgene escape from future genetically engineered varieties is another potential hazard. To assess the impact of these factors gene flow needs to be measured. A set of 10 simple sequence repeat markers have been developed, which exhibit polymorphism across a range of pigeonpea varieties. Use of these markers also offers an efficient system for the assessment of genetic diversity within populations of pigeonpea.
