Abstract: The effects of some factors of the culture conditions on the production of albino pollen-plantlets of rice were studied. During the Sustained subcultures, a few calluses, derived from somatic cells or pollensmight differentiated into green plantlets and a few as well Most of the calluses, however, gave rise to plantlets with relatively consistent colour differentiation. It was found that there was no regular correlation between the frequency of the albino pollen-plantlets production and the culture factors. 2,4-D at high concentration (20 mg/l) was the only constituent of the culture medium which apparently could promote the production of albino plantlets. It was found that the temperature for culture appeared in close correlation with the production frequency of albino pollen-plantlets, such as within certain range, the higher temperature was raised, the more the albino plantlets were produced. There was no correlation, however, between the intensity of illumination and the production of albino plantlets. The origin of albino plantlets was discussed. Before the origin of albino plantlets bas been understood completely, to control the temperature strictly may be decrease the frequency of albino plantlet formation.
