Inheritance of time to flowering in cowpea (Vigna unguiculata (L.) Walp.). Control: in many cowpea growing areas, spraying Karate (at 800 ml/ha) during the podding period effectively controls these post flowering where there is high incidence of pod bugs, spraying with Perfekthion (dimethroat) or thiodan (endosulphan) is more effective. Sufficient seed of F1, F2, F3 and backcross populations were generated. 10. CB27 began flowering 44 days after planting, while IT97K‐556‐6 delayed flowering until after 70 days. Twenty-nine diverse genotypes of cowpea (Vigna unguiculata) were grown in approximately 30 photothermal environments in Nigeria and Niger, with mean temperatures ranging from 19° to 30°C, photoperiods from 10 to 16 h d −1 and saturation deficits from 0.5 to 3.1 kPa.Twelve of these genotypes were insensitive to photoperiod.

Time of flowering is particularly of great importance in annual crops, including cowpea (Vigna unguiculata [L.] Walp), as it is a component of the adaptation of a variety to a particular environment and it also determines pod set and crop yield (Ishiyaku et al. Vince-Prue, D., 1975. Phyllochron in wheat as affected by photoperiod under two temperature regimes. Walp.) DOI: 10.3923/IJPBG.2012.1.16 Corpus ID: 87937526. In Australia, the ideal time to cut a cowpea crop for hay is at peak flowering, which occurs 70-90 days after sowing (Cameron, 2003). Hayman, B.I., 1958. Photoperiodism in Plants. J Hered 73: 306–308. The scatter plot and cluster means of the first two principal axes grouped the cowpea accessions into two main clusters, based on their response to day-length.
