Report 1979

Autor: Temple, S Schwartz, Howard F. Morales, Francisco José Cardona Mejía, César Schoonhoven, Aart van

The main priority of efforts in genetic improvement of beans is to increase the production in areas where it is currently cultivated. The environment in those areas has unfavorable climatic conditions for the crop and instead, favorable for the disease- insect complex attacking it. Through the co...

White mold, caused by the fungus Sclerotinia (Whetzelinia) sclerotiorum, is distributed worldwide and has more than 300 hosts. It infects flowers, cotyledons, seeds, leaves or injured plant tissue. The disease can be controlled by crop rotation, flooding, reduced seeding rates, application of che...

Among the bacterial diseases that attack beans are (1) halo blight (Pseudomonas phaseolicola), which is distributed worldwide and survives in infected seeds and blunt residue. Three to five days after infection, water-soaked spots appear on the lower leaf surface, stem and pods; (2) bacterial wil...

Investigations were conducted at CIAT to develop methodology required to evaluate resistance to Isariopsis griseola inherent in bean germplasm and breeding progeny. Abundant sporulation by the pathogen has been achieved by growing isolates in the lab. on V-8 medium incubated at 19 degrees Celsius...

A description is given of the format of the International Bean Rust Nursery (IBRN) established during a 1974 workshop of research workers from various countries. The objectives of the IBRN are to (a) identify cv. and breeding lines resistant to a wide spectrum of the pathogenic potential inherent...

Bronzing was observed in many of the bean trials conducted at Fort Collins (Colorado, USA) during 1982 to study the influence of water and shading stress on photosynthesis and protein content of 3 dry bean var., Roza, Pinto U.I. 111, and Olathe. Bronzing symptoms appeared during the late flowerin...

Data obtained from the international Bean Rust Nursery (IBRN) in 1975-76 showed that none of the 132 cv. and breeding lines tested was resistant to bean rust; however, some were susceptible only in specific geographical regions. CIATs bean program has concentrated its efforts on selecting rust-re...
