In the same time we are doing 10 generation of soybean breeding near Sanya on Hainan Island during the October to May. We made cross 398 combinations and a lot of propagation of soybean elite. We select a best local popularized variey for cross with soybean variety with 1-2 best character for breeding, for example high yielding, high oil or high protein content, high resistance to nematode and others We made alternate breeding in North and on South. In the same time we test breeding materials in two conditions: soil with high fertility and low fertility. Finally, we released two soybean cultivars: Zhonghuang 12 and Zhonghuang 13,and two cultivars will released this year. We test more than 10 soybean lines in 15 provinces. We got a good line with high oil content and high protein content. And we developed several soybean lines resistant to soybean cyst nematode.展开更多
