dc.description.abstractPotential of this wild co flee can be utilized as gcneiic resource for coffee breeding program and/or domeslicalion but iintbriunalcly ihe population struciurc. propagation poienlial and genetic variability of the discovered Kihansi wild co flee is poorly known. 1'herefbre. characlerizalion and population study is highly needed hence, this study aims to (i) Assessing the population chnamics of Coflea kihunsiensis (ii) Optimizing vegetative propagation of Coffeu kihansiensis (iii) Characterizing morphological traits of Kihansi wild coffee kiluuisiensis) and (iv) Assessing lhe gcneiic diversity of Kihansi wild co Hee. Populaiion dynamics assessment using quadrat method was done. Variability of population density, lowest in lower upper and upper block while highest population density was observed in lower spray. High proponional of matured plant were observed in both two seasons wiih lowest number of dead plants. In optimizing vegetative propagation, sand as propagation media provided promising results with good rooting ability, high survival rate and highest root number compared to decomposed rice husks (DRH) and un-dccomposcd rice husks (UDRH). About 62.52 % and 72.42 % population variation detected based on vegetative and icpioduciive traits respectively. Plant habit. branching habit, angle of* primary branches, berr、and cherry length, width and diameter are lhe most signiilcant traits expressed the morphological variations. These variations were confirmed in genetic diversity study using SSK markers. About 97 % of the total variation was detected within populations. Four clusters varied at 60 % were obtained. These findings are useful in planning conservation and management strategies while providing insight on utilization of this coffee as genetic resource for coffee improvement. Key words: Coffeu kihansiensis. genetic variability, population density and improvement.
