| Abstract: | Based on the climatic characters of semi - arid district in North China, by use of the new strategy of breeding, six kinds of intersectional hybridization combination have been finished with filial generation Ft as the parents, which have been cultivated in recent 20 years, in order to cultivate the filial generation F2 with strong stress resistance, fast growing and good material. Five kinds of good hybrid parents have been determined, and two kinds of hybrid combination with strong affinity have been determined. |
