Furthermore, studies of floral biology and pollination ecology, historically, have been biased towards visual aspects of floral phenotype, and most humans typically lack a reliable vocabulary with which to characterize odour and communicate its qualities (Raguso, 2008). An anther includes 4 elongated sacs where pollen grains are stored. Each unit of inflorescence is spikelet. Lateral roots are formed from the seminal root. Knowledge of floral biology, which includes structural and functional aspects of rice flower is essential for breeders to plan and execute breeding and hybrid seed production strategies.

Increasing productivity and yield stability, as well as improving the efficiency of breeding programmes, requires to understand the parameters that affect the duration of the flowering period, the pollination and the seed set. Studies in floral biology are largely concerned with how flowers function to promote pollination and mating. The first spikelet to flower is generally in the middle third of the spike and usually near the upper part of this section; the flowering progresses rather rapidly upwards, downwards a little slower. Oryza sativa contains two major subspecies: the sticky, short-grained japonica or sinica variety, and the nonsticky, long-grained indica rice [ja] variety.
