 note = {In 1982, the writer was sent to Fiji as a member of the scientific survey team for
a joint work with Kagoshima University and the University of the South Pacific. In
this opportunity, 20 strains of Oryza sativa L. were collected during the trip. In this
paper, some records on morphological characters of the grains and some considerations on ecotypic differentiations have been described, for searching the varietal variations of cultivated rice strains using in Fiji at the present. The results obtained here were
summarized as follows:
According to the tripartite classification, they were classified into two groups, i.e.,
type B — 7 strains (35% of the whole strains) and type C — 13 strains (65%). Length, width, thickness, L/W, L/T and W/T of the unhusked grains were measured as 8.71mm, 3.00mm, 2.12mm, 2.93, 4.13 and 1.42 in strain averages, respectively. Those of the husked grains were measured in the same order as 6.16mm, 2.47mm, 1.90mm, 2.50, 3.26 and 1.31 in strain averages, respectively. Nineteen, 3 and 2 characters showed larger,
smaller and the same values in type B than those of type C, respectively.
The maximum, the minimum and the pure-range of length, width, thickness, L/W,
L/T and W/T in the unhusked grains were ascertained as 9.22mm, 8.19mm, 1.03mm;
3.19mm, 2.81mm, 0.37mm; 2.26mm, 1.96mm, 0.30mm; 3.22, 2.67, 0.54; 4.48, 3.80,
0.67; 1.57, 1.29, 0.29 in average values, respectively. Those in the husked grains in the same order were ascertained as 6.50mm, 5.78mm, 0.72mm; 2.64mm, 2.31mm, 0.33mm; 2.02mm, 1.74mm, 0.28mm; 2.75, 2.30, 0.45; 3.57, 3.00, 0.56; 1.46, 1.19, 0.27 in
average values, respectively. Twenty seven, 8 and 1 characters showed larger, smaller
and the same values in type B than those of type C, respectively.
Basing on the data obtained in those characters, several patterns were found to be
strain specificities. Strains showing relatively large or small values in the respective characters were picked up and grouped as "order" and "combination".},
