Abstract
Primitive cultivated wheat, Triticum monococcum, is often viewed as a source of genes to be used in dumm and bread wheat breeding programmes. In the present study, two chlorophyll b-deficient mutants of T monococcum were used to analyze the consequences faced by chlorophyll fr-deficient mutation. We assessed inheritance of chlorophyll b-deficient mutants, “purple mutant” and “moegi mutant” Both mutations are determined by different single recessive genes. “Moegi mutant’ is one of the chlorina mutations based on light environmental effect on chlorophyll accumulation. A striking difference was found between the wild type and “purple mutant which had much higher Opsnand electron transport rate (ETR) at the given level of absorbed photon irradiance. It can be attributed due to the severe reduction of in PSII antenna size in the absence of LHCII.
