✦ Synopsis

The percentage of green plants in anther culture is known to be controlled by the genetics of anther donor materials. The objective of this study was to determine whether components in the culture media also would have a significant influence on the percentage of green plants from wheat anther culture. Anthers of a spring wheat cultivar, "Pavon 76", were cultured on potato 4 (P4) induction media with various modifications. Addition of 200 g/l ficoll to the liquid P4 medium significantly increased the percentage of green plants even though the final yield of green plants per 100 anthers was lower than the liquid medium. A higher concentration of maltose (135 g/l) produced significantly higher percentage of green plants than the medium containing 90 g/l maltose or sucrose. These results demonstrate culture medium effects on albinism, indicating that the percentage of green plants in wheat anther culture can be increased by optimizing medium osmotic potential.
