Report 1981

Autor: Gepts, Paul L.

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...

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...

Studies on the biology and damage caused by bean pests Diabrotica balteata and Cerotoma facialis have been conducted at CIAT since 1977. The biology of the 2 species is similar in many aspects. Life cycle is as follows: eggs, 6-7 days; 1st larval instar, 3-4 days; 2nd instar, 2-3 days; and 3rd in...

The method of selection used by CIATs climbing bean program is between the pedigree method (lineage) and the bulk population method. This method reduces the variation of each hybrid population in F, by individual selection. The evaluation of the germplasm bank was conducted in Popayan (1850 m abo...
