Ten rice varieties released during the last four decades of research in Andhra Pradesh did not differ significantly in photosynthetic rates as well as fluorescence. However, the accumulation of 14C was relatively more in grains of varieties released during 1980s and 1990s than those of 1960's and 1970's. The AGP-ase activity in the grains was significantly more in varieties released after 1970s compared to earlier ones.
