Sources and inheritance of earliness in tropically adapted indeterminate common beans

Autor: White, Jeffrey W. Singh, Shree P.

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...

Metodología para la selección de líneas de fríjol Phaseolus vulgaris L. por estrés de temperatura a nivel microgametofítico

Autor: Vásquez, L.M. Montes Rojas, C White, Jeffrey W. Roca, William M.

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...

Use of grafting to characterize and alleviate hybrid dwarfness in common bean

Autor: White, Jeffrey W. Montes, C Mendoza, LY

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...
