【摘要】 南夏豆46是由南充市农业科学院选育的超高蛋白夏大豆新品种。2022年通过四川省农作物品种审定委员会审定，审定编号为川审豆20223003。2019—2020年参加四川省特殊类型套作大豆自主区域试验，两年平均产量1 451.7 kg·hm^-2,较对照贡选1号增产3.0%;2021年参加套作大豆生产试验，平均产量1 462.05 kg·hm^-2,较对照贡选1号增产4.5%。籽粒粗蛋白质含量45.4%,粗脂肪含量16.7%,属高蛋白大豆新品种。抗性鉴定结果：中感SC3、感SC7大豆花叶病毒生理小种。种皮黑色，是四川省第一个通过套作审定的黑皮大豆新品种。2021年参加四川省净作大豆品种展示比较试验，平均产量2 227.5 kg·hm^-2,较对照南夏豆25增产9.2%,增产显著，适宜净作。适宜在四川省平坝、丘陵及类似生态区套作和净作种植。更多还原

【Abstract】 Nanxiadou 46 is a new suitable summer-interplanted high protein soybean variety which breed by Nanchong Academy of Agricultural Sciences. It was approved by the Crop Variety Examination and Approval Committee of Sichuan province, and its Accreditation Number is Chuanshendou 20223003. During the year of 2019 to 2020 regional test of spring maize-soybean relay intercropping of Sichuan province, the average pod yield of Nanxiadou 46 was 1 451.7 kg·ha^-1,increased 3.0% more than that of Gongxuan 1（CK）. The average pod yield of Nanxiadou 46 was 1 462.05 kg·ha^-1, increased 4.5% more than that of Gongxuan 1（CK） in production test of relay intercropping in 2021. Nanxiadou 46 is a new high protein soybean variety of which the content of crude protein and fat in seed was 45.4% and 16.7%, respectively. It is moderately susceptible to soybean mosaic virus strains SC3 and susceptible to SC7. Its seed coat is black, it is the first black soybean variety suitable for the relay intercropping system approved by Sichuan province. The average pod yield of Nanxiadou 46 was 2 227.5 kg·ha^-1, increased 9.2% more than that of Nanxiadou 25（CK） in adaptation test of sole cropping in Sichuan province in 2021. Thus, Nanxiadou 46 is suitable for interplanting and sole-planting in Pingba, hills and similar ecological areas of Sichuan province.更多还原
