Abstract
The number of days to first flower was recorded for parents and F2 of dry bean crosses 'Bulgarian White' X each of 'GN Ul 59', 'ON D-88', 'GN 114O,1 and 'GN Emerson1 X 'GN D-88'. The populations were grown n the field under the same long photoperiod and approximately the same day temperatures, but different night temperatures at Lincoln and Scottsbluff, Nebraska. 'Bulgarian White' was much later In flowering than the other parents at Scottsbluff than at Lincoln. All parents showed only limited response to photoperiod in growth chambers. It is hypothesized that days-to-fk>werlng was controlled by alleles at a single locus at Scottsbluff. Transgressive segregation for late flowering plants occurred In all F2 generations at Lincoln indicating that more than one gene was involved and a 13:3 ratio indicated action of two genes in one cross, ft Is suggested that only one gene was active under lower night temperatures at Scottsbluff while more than one gene was activated under high night temperatures at Lincoln.
