Performance of soybean genotypes after virus inoculation

Twenty genotypes of soybeans that were obtained from the germplasm of Bangladesh Agricultural University's genetics and plant breeding farm laboratory were checked for the presence of the soybean yellow mosaic virus (YMV).This table displays the percentage of infection and AUDPC (Area Under Disease Progress Curve) for each genotype derived from the scores at 7, 10, and 14 dpi (days post inoculation) following virus injection. Susceptibility was shown by the high value of % infection and AUDPC, whereas resistance was indicated by the low value. Therefore, it is possible to classify the following as extremely resistant: Davis, Lokon, G-10180, Asset 93-19-5, G-2120; moderately susceptible: AGS-66; highly susceptible: TAINANS; and highly resistant: MINA-HAI, Shohag, HIHS-WIHS, BS-3, BRAGG.

本研究以从孟加拉国农业大学遗传学与植物育种农场实验室种质资源库获取的20份大豆基因型为材料，开展大豆黄花叶病毒（soybean yellow mosaic virus, YMV）侵染检测。本表格呈现了基于病毒接种后第7、10、14天（days post inoculation, dpi）的调查评分计算得到的各基因型的侵染率与病害进展曲线下面积（Area Under Disease Progress Curve, AUDPC）。侵染率与AUDPC数值越高，对应基因型的感病性越强；数值越低，则抗病性越好。据此可对供试材料进行抗病性分级：高抗（extremely resistant）材料包括Davis、Lokon、G-10180、Asset 93-19-5、G-2120；中感（moderately susceptible）材料为AGS-66；高感（highly susceptible）材料为TAINANS；另有高抗（highly resistant）材料包括MINA-HAI、Shohag、HIHS-WIHS、BS-3、BRAGG。
