Bamboo shoot nutrient components of 30 hybrid families of Dendrocalamus latiflorus Munro were tested in order to investigate variation of the descendants.Results showed that there were great variations in the content of water-soluble carbohydrates,starch,free amino acid and protein among different family,the CV of these indexes were 23.69%,26.70%,38.26% and 15.76%,respectively.Proportion of essential amino acid exceeded 30% in all families and fluctuated from 33.80% to 42.97%.All families could be classed into 3 clusters on basis of similarities of contents of water-soluble carbohydrates,starch,dissociate amino acid,protein and proportion of essential amino acid,11 families,included in the cluster I and cluster II,were excellent families of nutrient quality with higher contents of free amino acid,protein and proportion of essential amino acid，10 of them had the common parent JD or HK origin at least.It indicated that bamboo shoot nutrition of Dendrocalamus latiflorus was controlled by genetic,excellent hybrids at nutrient quality could be obtained through cross with suitable parents.
