Not only attractive as a model plant, foxtail millet [Setaria italica (L.) P. Beauv] is a nutritious cereal. S.italica is tolerant to dry land but is less adaptive to shaded environments. Expanding this cereal's planting area through an intercropping system is part of its conservation as underutilized cereal in Indonesia. Buru Kuning is one of the superior foxtail millet accessions from Maluku. The study aimed to improve Buru Kuning accession productivity in shade conditions through radiation. This study was arranged in a Nested Design. The main plot was the different levels of shading (full light, 55% shade, and 75% shade). The subplot was the dose of Gamma Rays (wildtype of Buru Kuning, 25 Gy, 50 Gy, 100 Gy, and 200 Gy). The results showed that shade conditions decreased plant growth and production compared to full light. The results revealed that dosage 25 Gy radiation effectively improves Buru Kuning accession tolerance to shade without loos its prominent characters. Mutant 25 Gy adapted better than wildtype to 55% reduced light intensity recommended for developing in the intercropping system cultivation. [ABSTRACT FROM AUTHOR]
