Respon Beberapa Genotipe Kedelai Terhadap Infeksi Cpmmv (Cowpea Mild Mottle Virus)

Response of various soybean genotipes against cowpea mild mottle virus (CPMMV) infection. The green house experiment was conducted to investigate the effect of CPMMV infection on growth and yield of various soybean varieties. Treatments were arranged in completely randomized block design in split plot experiment. Mainplots were virus-inoculated and uninoculated plants; subplots were eight soybean varieties: Wilis, Orba, MLG 2521, Taichung, B 3570, Dieng, Tidar, and Pangrango. The results of this experiment showed that CPMMV infection decreased vegetative growth and yield of soybean plant. The decrease of dry weigth of soybean plant proved that CPMMV infection inhibited the vegetative growth. Taichung variety susceptible to CPMMV was indicated by significant reduction of the growth and yield. B3570 line tolerance to CPMMV infection was proved by lower reduction of the yield
