There were eight buffalograss(Buchloe dactyloides)parents, four male and female each, by incompletely diallel cross design, the degree of turning yellow,leaf color of the parents and the offsprings were determined. The heterosis of the degree of leaf turning yellow and the leaf color were also mensured. The heterosis of buffalograss leaf turning yellow was low, difference existed in the heterosis of leaf color. And the same parent had different heterosis value in different cross groups.
