Annual progress report : July-Dec., 1973 (terminal)

PRINCIPAL ACTIVITIES ENTAILED ACQUAINTING PERSONNEL OF THE UNIVERSITY OF PUERTO RICO WITH THE PROJECTS IN PROGRESS AND ARRANGING FOR THE ADMINISTRATIVE TAKEOVER BY THE UNIVERSITY, UNDER WHOSE AUSPICES THE GRAIN LEGUME RESEARCH WILL CONTINUE. TIME WAS ALSO SPENT IN ANALYZING DATA FROM THE VARIOUS PROJECTS AND PREPARING PUBLICATIONS, AS WELL AS CLASSIFYING AND CATALOGING THE SEED COLLECTION. STUDIES WERE CONTINUED WITH BACTERIAL BLIGHT OF BEANS AND COWPEAS, AND THE ROLE PLAYED BY INSECTS IN THE SPREAD OF THESE BACTERIAL PATHOGENS. NUMEROUS COLLECTIONS WERE MADE OF INSECTS IN BACTERIAL BLIGHT-INFECTED BEAN AND COWPEA PLANTINGS. ONLY A FEW INSECTS COMMONLY CONSIDERED PESTS OF THE FOLIAR PORTIONS OF THESE TWO FOOD LEGUMES WERE FOUND TO BE VECTORS OF BACTRIAL BLIGHT UNDER NATURAL FIELD CONDITIONS IN PUERTO RICO. THE MOST IMPORTANT INSECT VECTORS WERE DIAPREPES ABBREVIATUS AND CEROTOMA RUFICORNIS. THIS REPORT PRESENTS 25 SUMMARY STATEMENTS OF FINDINGS FROM A SURVEY OF DISEASES AND PESTS OF BEANS AND COWPEAS IN CENTRAL AMERICA AND THE CARIBBEAN. ALSO INCLUDED ARE 17 STATEMENTS OF FINDINGS FROM RESEARCH STUDIES OF FUNGAL AND BACTERIAL DISEASES OF THESE LEGUMES. A TABULAR SUMMARY OF THE ORIGINS AND NUMBERS OF CULTIVARS ASSEMBLED IN THE SEED ACQUISITION PROGRAM AND STORED IN THE GERMPLASM BANK AT FES, MAYAQUEZ, PUERTO RICO, IS ALSO PRESENTED. THE FINAL SECTION OF THE REPORT DISCUSSES SHORT-TERM AND LONG-TERM PROBLEMS AND COMPLICATIONS ASSOCIATED WITH RESEARCH ON BEAN AND COWPEA PATHOGENS IN CENTRAL AMERICA, THE CARIBBEAN, IRAN AND INDIA.
