• In order to reconfirm the influence of the producing places especially meteorological conditions upon the chemical components and the disposition structures of starch-cells in the cross section of rice kernels, chemical analyses and observations were made on specimens of the "Koshihikari" variety (the "nanshitsu-mai" type), lowland rice plants cultivated on a standard basis at a lowland rice field attached to the Fukui University as well as those supplied from the lowland rice crop situation experiment stations, Ministry of Agriculture, Forestry and Fisheries of Mito, Chiba, Mie, Miyazaki and Nagaoka for the 4 years between 1975 and l978. It was shown from the above inquiry that some difference in the producing places especially in meteorological conditions serves to produce a difference in the chemical components and the disposition structures of starch-cells in the cross section of rice kernels even on the same variety, that a line of demarcations is to be drawn in this respect, namely in the difference of (P) (Protein-N/Crude starch (each in dry basis %) × 100) and (T) (Soluble-N+Total Sugar (each in dry basis %)), between specimens from soft and hard-textured rice producing areas, that meteorological conditions, especially amount of solar radiation, sunshine hours and air temperature, during each 5 half decades before and after heading stage, exert considerable influences, and that meteorological conditions, especially the sames as above, during 2 or 3 half decades after heading stage, exert great influences upon the disposition structures, while originally it forms the essential characteristic of a rice variety. It was revealed that meteorological conditions have a serious effect-too serious to be ignored after all. Our finding served to point to the identical trend as our reports so far made on other varieties, thus reaffirming the truth of our reports hitherto made.
