The photothermal flowering responses of 25 diverse genotypes of common bean (Phaseolus vulgaris L.) were examined in 25 African Bean Yield Adaptation Nurseries (AFBYAN) in the Eastern, Southern and Great Lakes regions of Africa during 1988 and 1991. The trials were located at latitudes between 0....

The angiosperm circadian clock has been well established from molecular-genetic studies in a temperate plant model. Conservation of clock function is less explored in plants from the tropics. Cassava (Manihot esculenta) is a staple crop grown in the tropics that has been of limited research inter...

The genetic basis of the photoperiod response in common bean (Phaseolus vulgaris L.) was investigated using DNA markers and recombinant inbred populations. Two loci affecting photoperiod response were resolved, the previously defined primary locus (Ppd), at which the dominant allele confers sensi...

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...

The seed yields and limitations to yield for nine pasture legumes in a tropical savanna region were defined in a 3-year field experiment at the Cerrodos Agricultural Research Centre near Brasilia (15°36' S, 47° 42' W). Assessment was based on flowering times, incidence of diseases and pests, yiel...

The seed yields and limitations to seed production for four tropical grass cultivars were defined via a replicated field experiment conducted over three years at the Cerrados Agricultural Research Centre near Brasilia (latitude 15° 36' S; longitude 47° 42' W) in a tropical savanna region. The fou...

Cassava is a tropical storage-root crop that serves as a worldwide source of staple food for over 800 million people. Flowering is one of the most important breeding challenges in cassava because in most lines flowering is late and non-synchronized, and flower production is sparse. The FLOWERING ...

In the Guatemalan localities of Chimaltenango and Cuyuta (19 and 29 degrees Celsius, resp.), the F2 populations from 6 crosses (ICTA Quetzal x JU 80-11, ICTA Quetzal x San Martin, ICTA Quetzal x Rabia de Gato, JU 80-11 x San Martin, JU 80-11 x Rabia de Gato, and San Martin x Rabia de Gato) were o...
