A good pollinator for hybrid wheat production .hould posse.s high pollen productivity
and ability to extrude anthell in addition to favourable combining ability and fertility
restoration properties. Anther length, efficiency of pollen production, and intensity of
anther extrusion were studied in four exotic restorer lines of spring wheat. The lines
significantly differed in size of anthers, number of pollen grains/anther and per cent of
anther extruded. Correlation coefficient between anther length and number of pollen
grains/anther was significant (r '"' 0.97), while nonsignificant negative correlation (r. ~.05)
was observed between anther length and antherextrusion percentage. The knowledge that
genotypes with large anthers also produce many pollen grains per anther facilitates the
selection of a high pollen donor.
Keywords: Triticum aestiwm, pollen production, anther length.
