Genetic diversity in Napier grass (Pennisetum purpureum) assessed by SSR markers.

摘要: Understanding of genetic diversity among Napier grass is very important for selection and improvement breeding population. This study determined the farmer preferred, wild (local) selected ILRI gene-bank clones using 23 SSR markers from pearl millet, maize sorghum. The results indicated polymorphism markers, revealing a total 339 alleles which 27.1% were unique, occurring either only in local, farmers preferred or clones. Similarly, observed heterozygosity highest local than farmers’ least clustered two groups with few overlaps, although most farmer’s grown grouped those genebank clone P99, emphasizing their relatedness. Therefore, unique revealed may be associated adaptability to environments. These could, therefore, exploited grass.
