Abstract:The reproduction fitness of plant population represents the adaptive ability of plant reproductive behavior to the environmental change and the contribution of plant reproduction to population regeneration.The fitness of reproduction is reflected both on the individual level and on the gene level.One set of formula were built to measure the fitness of seed reproduction and vegetative reproduction on the individual and gene level,and the fitness of white clover was calculated with the new formula.The results show that the new formula illuminate well the different contribution of seed reproduction and vegetative reproduction to the that regeneration of clone plants
Keywords:clone plant  seed reproduction  vegetative reproduction  fitness
