%X Fourteen genotypes of Indonesia cassava (Manihot esculenta Crantz) of two generations were evaluated for ¦Â-carotene content. The ¦Â-carotene content of tubers and leaves were determined by spectrophotometry method. Other parameters such as water and ash contents were also evaluated. Results showed that ¦Â-carotene content of tubers of fourth generation (planted in 2006-2007) was higher than that of first generation (planted in 2002-2003), with the exception of Apuy, Iding and Sarewen genotypes. ¦Â-carotene content of tubers was lower than that in their leaves of fourth generation plants and that there was no correlation between both organs in terms of ¦Â-carotene content of tubers and their leaves except for Tim-Tim 40 genotype. ¦Â-carotene content of tubers in several genotypes i.e. Kalbar III (1.13 ppm), Local Muneng (1.03 ppm), Tim-Tim 29 (1.61 ppm) was higher than 1 ppm, and the highest value was found in Tim-Tim 40 (16.83 ppm) which was significantly different (5%) with other genotypes. Meanwhile the lowest content was found in Sarewen genotype as it could not be detected. Water and ash contents of the tubers were between 54 and 69% and between 0.20 and 0.79% respectively. As ¦Â-carotene is the precursor of vitamin A, consuming high ¦Â-carotene tubers are sufficient for daily requirements of vitamin A, although further study is needed.
