In order to study the relations between functional leaves features and yield, the functional features such as photoynththetic ablility, length of leaves and leaves area and their relation to yield were studied by using 17 rice varieties by introducing exogenous DNA. The results showed that 1 000 grains weight was negatively correlated to the length, area and photosynthetic ability of leaves, wheres the weight of single panicle was significantly positive correlated to the photosynthetic ability and area of functional leaves. The photosynthetic ability, which was not significantly correlated to ...
