Effect of plant growth conditions, plating density, and genotype on the anther culture response of soft white spring wheat hybrids.

Ten soft white spring wheat (Triticum aestivum L.) F hybrids were grown under three temperature regimes, and anthers were cultured at two plating densities to investigate the effect of plant growth conditions, plating density, and genotype on embryo induction and plant regeneration. Anthers from plants grown at high temperature (25 °/18 °C) or from plants transferred from low (15 °/12 °C) to high temperature generally produced more embryos and green shoots, with a lower frequency of albinos, than did anthers from plants grown at low temperature. However, plating densities of 10 versus 20 anthers per milliliter, had little effect on anther response. Four of the five hybrids with Fielder' as the female parent produced more embryos and green shoots than did hybrids with AC Reed' as the female parent.
