ABSTRACT
Soybean germplasm found resistant to two SMV isolates through mechanical inoculation under screen house conditions were exposed to field conditions. Among 13 soybean varieties, Malakand-96, Bryan and Sherman had no symptoms and no virus was detected by ELISA. Wahab-93, Lugan, Hobbit, Kingsay, Harper, Nare, NARC-V and Clark developed mild mosaic and light veinal chlorosis on a few young leaves. Rincondita and Swat-84 exhibited mosaic and vein clearing on many young leaves. Among soybean lines, GC-81083-63, GC-81084-51, GC-80072-2-6, AGS-253 and AVRDC-13, no visible host reaction was observed. On AVRDC-12 and AVRDC-15 responded mild mosaic symptoms were observed on a few leaves. Malakand-96, Bryan and Sherman and GC-81083-63, GC-81084-51, GC-80072-2-6, AGS-253 and AVDRC-13 lines were re-tested in screen house conditions by inoculating isolate S1 through green peach aphids (Myzus persicae). Three soybean varieties and four lines exhibited a mild mosaic on young leaves. A low virus titre was reported in resistant soybean germplasm.
