Disease free propagating materials with acclaimed quality traits are of huge demand in citrus. Citrus, a naturally polyembryonic group of plants produce seeds with more than one embryo with different combinations of zygotic and nucellar ones. Nucellar seedlings are the best option for having disease free propagules with desirable quality and high yielding ability. An experiment was conducted to study the effect of external treatments with different quality of light on development of seedlings from polyembryonic citrus seeds. Seeds of sweet orange, mandarin orange, lime and lemon were treated with three kinds of light : red, white and blue light. Observations were recorded on the parameters related to germination and the nature of seedlings. The result showed that nucellar seedling generation from the citrus seeds might be enhanced with the treatment of blue light in lime, red light treatment in lemon and white light treatment in sweet orange and mandarin orange.
