Ali, C.S.
Selection for early row-cropping pigeon pea plant types beginning with individual F3 plant selections, was successful in producing F6 families with improvement in earliness, dwarfness and with some degree of daylength-insensitivity. The effect of daylength/night-temperature combinations on vegetative and reproductive growth parameters in a number of F1 pigeon pea families was studied with the use of growth parameters. Results showed that genetic control of vegetative and reproductive growth components was highly influenced by both daylength and night-temperature but more by photoperiod. Studies on carbon dioxide enrichment showed increases in the overall plant biomass without affecting the allometric relationships within the plant or harvest indices.
