The parental lines of sorghum hybrids CSH 5, CSH 6, CSH 9 and COH 2 were sown at fortnightly intervals to study the flowering behaviour Correlations were worked out between the days to (i) panicle initiation, (ii; half-bloom and (iii) from panicle initiation to half-bloom on the one hand and the weather elements viz., maximum and minimum temperature, fore-noon and after-noon relative humidity, sun shine and rainfall that prevailed during the four phases of plant growth on the other.
