Abstract

Results of an experiment in Trinidad were analysed and data obtained from literature were recalculated to determine which factors control the DM distribution in the cassava plant. Under given conditions for long periods, possibly for the storage life of cassava, the distribution of DM over tubers and shoot proved to be constant. Based on this finding, a model was developed and 2 parameters were introduced: ESRP, efficiency of the plant at producing tubers; ISS, initial plant wt. at which tuber production starts. The model was used to visualize genetic differences and the effect of environmental conditions on DM distribution. The relation between harvest index and ESRP was discussed. It is recommended that ESRP is used instead of harvest index as a selection trait. Selection material on ESRP can be screened rather early in the growth cycle as tuber wt. is linearly related to plant wt. (Abstract retrieved from CAB Abstracts by CABI’s permission)
