 note = {In June and July of 1981, 29 strains of the cultivated rice species, Oryza sativa L.,
were collected and varietal variations in grain morphology were searched for.
Length, width, thickness, and ratios of length to width, of length to thickness and of width to thickness of unhusked grains were determined to be 9.03mm, 2.90mm, 2.07mm, 3.15, 4.40 and 1.41 in strain level, respectively. Those of the husked grains were
determined to be 6.45mm, 2.43mm, 1.84mm, 2.69, 3.55 and 1.33 in the strain averages, respectively.
In accordance with the tripartite classification, 4 strains were ascertained to be a type B (= large or javanica type) and 25 strains a type C (= long or indica type). Based on the data obtained in those characters, several patterns were fixed to be
varietal variations and strain specificities. In comparison with the data obtained in the present and previous papers, ecotypic and varietal differentiations were discussed on the basis of the values ascertained in geographical localities.},
