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...

Nineteen early maturing, indeterminate common bean parents were crossed with a tester line of normal maturity. All parents, F1 hybrids, F2's, and backcross generations were evaluated at CIAT-Palmira, Colombia. All 19F1 populations flowered and matured almost as early as the respective early paren...

Los trabajos realizados en varias especies de plantas revelan que una porción significativa de los genes que se expresan en el esporofito también lo hacen en el grano de polen, en consecuencia la presión de selección a nivel de polen debe conducir a modificaciones en caracteres cualitativos o cu...

Crosses between common bean genotypes from different centres of origin can result in F1 plants with dwarfing that is severe enough to prevent formation of F2 seed. This hybrid dwarfness is controlled by two complementary genes, Dl-1 and Dl-2. The dominant alleles at both loci must be present to c...

The slow progress made in the search for var. with higher levels of drought tolerance is partially due to the inefficient management of nurseries. At CIAT, screening for tolerance has evolved at almost all stages, from planning through the analysis of final results. This report describes several ...
