Abstract

  A practical option to address food security of the South-east Asian countries where rice (Oryza sativa L.) is a staple food has been exploitation of heterosis through commercial hybrid rice technology. Hybrid rice exhibits a yield advantage of 15 - 20% (or more than one ton of paddy per hectare) over the best traditional varieties in large-scale production worldwide. However, as opposed to the case of open-pollinated plants, it is difficult to reliably produce an acceptable quality of Hybrid seeds through the use of systems. Rice is strictly self-pollinated. There are several traits contributing to the hybrid seed production efficiency, such as days to heading, pollen load, pollen longevity, and morphological traits of floret, viz., size of stigma and style, stigma exsertion, stigmatic receptivity, spikelet opening angle and duration.
