This paper elaborated procedures of cassava breeding and research activities directly and indirectly related to cultivar developments of cassava in Lampung. The objectives of cassava breeding program in Unila are to develop superior cultivars: high yielding, high starch content, suitable for functional rice, suitable for bioethanol, and/or resistant to diseases/pests. Cultivar development of cassava consisted of three main steps, i.e., germplasm enhancement, selection, and yield trials. Germplasm enhancement in this breeding program was conducted by exploration, introduction, and sexual hybridization. Exploration and introduction were strarted in 2011 by collecting local clones, superior varieties, and/or breeding lines from East Java (Balitkabi), Central Java, West Java, and Lampung. Cultivar development of cassava consists of germplasm enhancement, clonal evaluation and selection, and yield trials. Germplasms (clones) has been introduced and collected from East Java, Central Java, and Lampung Province; the clones have been evaluated in yield trial and for the parents of sexual hybridization. Diverse F1 populations was obtained as the result of sexual hybridization exemplified by the percentage recombinant type of the color of apical leaves in F1 populations derived from UJ 3, CMM 25-27, and Malang 6 as female parents (50%, 73%, and 73% respectively). Clonal evaluation is being conducted on 1617 F1 plants (clones) in 2016. CMM 97-6 was one of the high yielding clones selected from yield trial; 15 unit of prelimenary yield trial is being done in 2016. Keywords: Botanical seeds, breeding, clones, Manihot esculenta, sexual hybridization
