Abstract: Lose green specific Mutants lgs(t) partially or completely whitened at the seedling stage was isolated from natural mutation. The leaf turns to irregular green and white stripes at tillering stage. For studying the mechanism of leaf color mutation and the prospects of utilizing. Physiological and agronomic characters were investigated and genetic analysis. The results showed that, loss of green was closely related to chlorophyll content, which appears significantly low. Albino phenomenon made the soluble sugar content decreased and increased the free amino acids, thereby affected the yield traits of seed-setting rate and 1000-grain weight. Genetic analysis showed that the trait was controlled by a single recessive nuclear gene.
