Twenty-three accessions of Centrosema pubescens selected for good performance on an infertile, acid soil were tested along with 2 control lines each of C. pubescens and C. acutifolium at 18 locations in tropical America and one location in tropical China. The sites represent 3 major agroecosystem...
