| 1 | Qualification of Soybean Responses to Flooding Stress Using UAV-Based Imagery and Deep Learning显示文摘Soybean is sensitive to flooding stress that may result in poor seed quality and significant yield reduction.Soybean production under flooding could be sustained by developing flood-tolerant cultivars through breeding programs.Conventionally,soybean tolerance to flooding in field conditions is evaluated by visually rating the shoot injury/damage due to flooding stress,which is labor-intensive and subjective to human error.Recent developments of field high-throughput phenotyping technology have shown great potential in measuring crop traits and detecting crop responses to abiotic and biotic stresses.The goal of this study was to investigate the potential in estimating flood-induced soybean injuries using UAV-based image features collected at different flight heights.The flooding injury score(FIS)of 724 soybean breeding plots was taken visually by breeders when soybean showed obvious injury symptoms.Aerial images were taken on the same day using a five-band multispectral and an infrared(IR)thermal camera at 20,50,and 80 m above ground.Five image features,i.e.,canopy temperature,normalized difference vegetation index,canopy area,width,and length,were extracted from the images at three flight heights.A deep learning model was used to classify the soybean breeding plots to five FIS ratings based on the extracted image features.Results show that the image features were significantly different at three flight heights.The best classification performance was obtained by the model developed using image features at 20 m with 0.9 for the five-level FIS.The results indicate that the proposed method is very promising in estimating FIS for soybean breeding. | Jing Zhou Huawei Mou Jianfeng Zhou Md Liakat Ali Heng Ye Pengyin Chen Henry T.Nguyen | 2021 | Plant Phenomics2021，3，1： | 2 |

| 10 | 对“Archer”大豆中瓜果腐霉引起的腐霉猝倒病抗性遗传基因图谱研究显示文摘腐霉猝倒和根腐病引起大豆出苗率严重减少,因此造成减产。有报道认为大豆品种Archer对由腐霉菌引起的苗期病害具有抗性,并描述了与之相关的Rps1k基因对疫霉菌具有抗逆性。为了描述大豆品种Archer抗腐霉猝倒病的遗传特性,并且确定该抗性是否与Rps1k基因相关,Archer和Hutcheson(感病亲本)进行杂交,F2:4体(子二代)产生。 | 向新华 M.Luciana Rosso John C.Rupe Pengyin Chen Leandro A.Mozzoni | 2015 | 大豆科技2015，0，1： | 0 |
