Anthropological work carried out by the PROFRIZA project in Cusco over 2 cropping seasons, between 1988-90, are reported. The status of bean cultivation in the region was assessed, as well as the experience acquired in seed production, small farmer management of farming activities, and the integr...
The concept of plant genetic variability is studied as well as how it should be treated and presented to the researcher, especially in the management of bean genetic resources. Given the spread of some crops such as soybeans and pods, searching for variability in the available genetic resources f...

Early generation yield testing in beans in monoculture and intercropped with maize
The effect of 2 daylength treatments (11 and 15 h) on stem elongation was determined in 5 indeterminate bean cv. (G 17650, G 2997, DOR 44, G 5475, and JU 80-11) under growth chamber conditions. Under the short day length, G 17650, a viny indeterminate var. showed the longest stem under all condit...

A study was initiated to determine the barriers that limit the transferences of genes between Phaseolus vulgaris and P. coccineus. The factors that determine the outcome of this crossing are the direction (success is greater when P. vulgaris is used as the mother parent) and the combination of pa...

CIAT is currently the world center for all the germplasm of the genus Phaseolus. The bean program has the main objective of increasing bean production and productivity. Germplasm improvement involves a program of evaluation and identification of genetic diversity, improvement through more effecti...

Common beans (Phaseolus vulgaris L.) are an important world crop with a relatively low productivity in most cropping systems. Physiological factors influencing yield are discussed in this paper with respect to field research in the tropics. The comparative earliness of the majority of the germpla...

A report is given on the 4 cultivated species of the genus Phaseolus, studying geographic distribution, taxonomy and morphology, agronomic characteristics and germplasm collection. The areas where Phaseolus vulgaris is extensively cultivated are North, Central and South America, Europe and E. Afr...
Root rots occur in all the zones where beans are cultivated in the world. Fusarium spp., Pythium spp., Rhizoctonia solani, Sclerotium rolfsii, and Macrophomina phaseoli are found among the responsable microorganisms. Each pathogen developes according to its own optimum conditions. Problems are gr...
