【Abstract】 Using “Heidou 2" which immune to the race 2 of Soybean Cyst Nematode (SCN) crossbreeded with “Huangsha soybean" which has high yield characteristic. We obtained some better cultivars of soybean. Then, we used laser irradiation to these cultivars and selected a variety with high yield, good quality, resistance to the race 2 of SCN,called “Dedou 99-16" which in black seed coat. In the year 2001 to 2003, we joined the variety comparision and regional test of Shandong province. Its yield hit 2739.0kg/hm 2, crude protein and crude oil content had reached the governmental standard of good quality soybean, and it had high resistance to the race 2 of SCN. It is suitable for planting in Huanghuaihai area.更多还原
