Abstract:

In order to lay a foundation for breeding high quality forage corn distant hybrids forage grass strain. by the analysis on biology characters, yield and nutritional quality of distant hybrids between temperate zone corn and teosinte, the paper tries to filter prominent distant hybrids between temperate zone corn and teosinte, The result shows that in temperate zone (Shandong province), filial generation have many advantages with more tillering, higher yield and better quality than the control. The reinto, TH-02-044 grass yield reaches 94355 kg/hm2,equals to 3-4 times of control variety, CP content of each hybridized strain is higher than control variety, among which TH-02-030 and TH-02-023 have significant difference from control variety, respectively reaches 11.18% and 11.65%. TH-02-044, TH-02-030 and TH-02-023 three strains have prominent characteristics on tiller number, biological output and nutritional quality aspects,which have potential to be a resource of fine quality forage grass.
