To formulate an efficient hybridization system for the improvement of Dioscorea rotundata (white guinea yam) the influence of tuber sett-weight on flowering was investigated. The results showed tuber sett-weights can be manipulated as a means of synchronizing anthesis in male plants and receptivity in female plants apart from multiple and staggered planting dates previously in use. Although plants from larger sett-weights initiate flower buds earlier than those from smaller sett-weights, there was no correlation between sett-weights and flowering intensity.
