A field experiment was carried out during Kharif 2016 at Saidapur  farm of University of Agricultural Sciences, Dharwad. The field experiment comprised of fourteen treatments with two replications in Randomised complete block design. The results revealed that second fortnight of December sowing 2016 (T14) recorded the lowest plant height (77.50 cm) and 92.00 cm by female (ICMA 9277) and male (TPRT 111) parental lines respectively. With respect to days to panicle initiation, days to fifty per cent flowering and days to complete floweringmore number of days (48.00) days) was taken for panicle initiation by female parent and 56.00 days by male parent when sown on first fortnight of June 2016 (T1). The female and maleparental lines took significantly more number of days 52.00 days and 64.00 days for fifty percent flowering respectively. While, for complete flowering more number of days to complete flowering was (66.00 days) in female parent and 74.50 days in male parent when sown during first fortnight of June 2016. The lowest number of days in male parental line and in female parental line for panicle initiation, fifty per cent flowering and complete flowering (days) was noticed in Second fortnight of December 2016 sowing (T14). The variation in the plant height at different sowing dates might be attributed by the prevailing environmental conditions at their growth phase besides genetic factor. In the sowings, taken during the month of June, July, August and September months delayed the flowering due to rainy days, non-availability of better sun shine hours and due to prevailing photo period nature, as flowering requires particular day length and temperature and also pearl millet is photosensitive and short day plant. Short day length induces early flowering. During the month of December, the day length is short this period favours early flowering. This was true with both the parents.
