(RA-CIAT)Summary: From. Feb. to May 1978, a field trial with 12 dry bean cv. was carried out at Ribeirao Preto expt. station (SP, Brazil) to evaluate the losses induced by BGMV attack. Plants with early infection (before flowering) and with late infection (pod filling), as well as healthy plants, were identified. No. of pods/plant, seeds/pod, yield, seed wt. and germination were measured. BGMV reduced all studied parameters, and with greater intensity in the earlier infection. The av. yield was reduced by 73 and 43 percent in early and late infections, resp. (AS)
