[Abstract]
Longzhonghuang 601 is a new soybean variety bred by crossing and pedigree method with the female parent Kaiyu 12 and the male parent Handou 5 in Institute of Crop, Gansu Academy of Agricultural Sciences and Institute of Crop Sciences, Chinese Academy of Agricultural Sciences. The average yield of Longzhonghuang 601 reaches 2 650.05 kg/hm2 and which is 17.13% higher than of the check Longdou 2 in soybean regional test during the 2012 — 2013 in Gansu provice. Its average yield is 2 002.50 kg/hm2 and which is 6.69% highest among all the tested samples, which is higher than Longdou 2 in 2014 in Gansu soybean production test. The plant height, pods per plant, seed weight per plant, weight per 100 seeds and growth period of Longzhonghuang 601 are 63.50~86.30 cm, 45.60~52.30, 15.80~22.60 g, 19.10~24.80 g and 115~128 days, respectively. As to quality characters of the variety, the seed protein(dry) and fat(dry) are 41.94% and 20.09%, respectively. By field identification, the result also shows that Longzhonghuang 601 is moderate-resistance to black spot. It is suitable to be grown in Central Gansu, including Irrigation Districts Along Yellow River, Longdong region.
