Abstract
In 8 V. subterranea selections from the International Institute of Tropical Agriculture, Nigeria, exposed to a range of photoperiods in greenhouse trials, 2 groups were distinguished: (a) day-neutral for flowering with fruit set delayed by long photoperiods; (b) day-neutral for flowering with fruit set inhibited by long photoperiods. Leaf area/plant at harvest was much greater with 14-h daylength (1293-2730 cm²) than with 11-h days (385-606 cm²). In a 2nd trial using a selection with compact, erect habit from Mali, the number of fruits/plant was greater under a regime of 6 weeks of long days followed by short days than with continuous long days. In a 3rd trial under various combinations of short and long days, leaf area/plant in selections from Mali and the Gambia was greatest under continuous 14 h daylength. Seed yield/plant was greatest with 42 d of 14 h + 21 d of 12-h + 38-40 d of 10-h photoperiods in the Malian selection and with 21 d of 14-h + 80-82 d of 10-h photoperiods in the Gambian selection
