Description Information on combining ability is derived from data on photoperiod sensitivity and time to 50% flowering in 7 parents and their 21 hybrids from a diallel cross of pearl millet (Pennisetum glaucum) grown at Patancheru during 1990-91 under normal and extended summer daylengths (12.5 h and 14.7 h, respectively), kharif normal daylength (13.5 h) and rabi normal daylength (11.6 h). The genotypes were also evaluated at Hisar, Haryana, during the rainy season in 1990 (14.2 h daylength). Photoperiod sensitivity was calculated as the percentage delay in 50% flowering under the summer extended daylength compared with the summer normal daylength. GCA effects for time to 50% flowering and photoperiod sensitivity were significant and negative for genotypes ICMP83401 and ICMP451, indicating that these parents may prove useful in the production of early flowering, photoperiod-insensitive progeny. The summer extended daylength nursery at Patancheru was effective in identifying material that exhibited delayed flowering in northern India due to photoperiod sensitivity.
