VARIABILITY IN FLORAL STRUCTURE AND FLORAL BIOLOGY OF FINGER MILLET (ELEUSINE CORACANA (L.) GAERTN.)

Published on

The variability in floral structure and floral biology was studied in 24 strains of
finger millet The inflorescence consisted of a cluster of variable number of spikes
called fingers. Each finger has two opposite rows of spikelets. A spikelet contains
variable number of florets. The florets are hermaphrodite, perfect except for the
terminal florets. The floret is covered by two large glumes, enclosed between a pair
of palea. The florets are in the axil of lemma. The androecium consists of three
stamens. The gynoecium is bicarpellary, unilocular with superior ovary. Near the
base of ovary two lodicules are present. There was a wide range of variation in
the length of anther, filament, stigma and style. Anthesis occurred between 1.00
a.m. to 6.00 a.m., the peak period of anthesis being between 3.00 to 5.00 a.m. The
pollen viability at the time of dehiscence of anthers ranged from 76.92 to 100 per
cent. The pollen remained viable for 20 minutes.
