dc.description.abstract | Understanding the genetic diversity existing in a germplasm collection is important to identify parental
combinations
with distinct gene sets that can be used in crossing to obtain superior hybrids. This study was carried out to evaluate the genetic
diversity in the Rwandan coffee germplasm using both RAPD and SSR markers and to determine any relationship between these
two markers. Varieties with resistance to coffee leaf rust and coffee berry disease as well as local cultivars in Rwanda were
used
for DNA extraction and subjected to PCR amplification. The highest values for genetic distances were obtained bet
ween BM 139
and HDT and between Harar and Catimor implying that these varieties were genetically quite distinct. The lowest values for
genetic distance were recorded between BM 139 and BM 71 and between Matinho and Rume Sudan implying that these varieties
were genetically fairly similar. A Pearson correlation of 55.52% was obtained between the two markers indicating a moderate
association between these two analytical procedures. It is recommended that crosses should be made between genetically distant susceptible and resistant varieties to derive hybrids that combine resistance with marked levels of heterosis particularly for yield | en_US |
