[Abstract]
Longzhonghuang 605 is new cultivar of soybean with stable yield, good adaptability and disease resistance, which was bred by genealogical method by crossing Zhongpin 03-5179 as female parent and Zhonghuang 30 as male parent by Institutes of Crops,Gansu Academy of Agricultural Sciences and Institute of Crop Sciences, Chinese Academy of Agricultural Sciences. In 2018 — 2019, the average yield in 2 a was 3 038.7 kg/hm2, 12.87% higher than the control cultivar Longdou 2 in the Gansu Soybean Regional Test. In 2020, the average yield was 2 958.0 kg/hm2, 16.04% higher than the control in the Gansu Soybean Production Test. The cultivar has high-yield and stable-yield, wide adaptability, drought resistance, disease resistance and lodging resistance. The content of crude protein was 405.0 g/kg and crude fat was 208.5 g/kg. No occurrence of mosaic virus or downy mildew or sclerotinia in field experiment for several years, identified resistance to soybean mosaic virus, moderate resistance to soybean gray spot. It is suitable to be grown in mid-later maturity and later maturity area of Gansu Province.
