Photoperiod insensitivity in the germplasm collection of beans (Phaseolus vulgaris) held at CIAT is found mostly in accessions from higher latitudes. Cold tolerance is found in accessions from the high Andes, but these are all photoperiod sensitive. A break in adaptation seems to occur at about 1...


Davis, J.H.C.Gniffke, P[The effect of photoperiod and temperature on yield in beans]The effect of photoperiod and temperature on yield in beans

Five bean cv. were exposed to natural daylength (approx. 12 h) and ambient temp., or to 6 h daylength, achieved by moving pots into a darkened room to determine their response to photoperiod. Cv. Mortino and Frijolica 0- 3.2 did not flower under the control conditions, but with the short day trea...
