内容記述

During the periods from October to November in 1984 and from August to November in 1985, the writer was sent to 7 countries of Africa, i.e., Madagascar, Tanzania,
Kenya, Nigeria, Ivory Coast, Liberia and Senegal, for collection of the wild and cultivated rices. During the trips, 175 strains of wild rice, i.e., 107 of Oryza longistaminata, 49 of O.breviligulata, 18 of O.punctata and 1 of O.brachyantha, were collected and many populations of them were observed. Their localities and habitats were reported briefly.
From the analyses of grain characters of the unhusked grains, average values and
those standard deviations in the whole strains were found to be 8.76mm±0.50, 2.47mm±0.18, 1.65mm±0.11, 3.57±0.28, 5.34±0.39 and 1.50±0.11 in length, width, thickness, ratios of length to width, of length to thickness, and of width to thickness, respectively, in case of the O.longistaminata. The largest and the smallest values in the respective characters were ascertained in Nigeria of 1984 (D mark in Table 2) and Kenya (C);
Nigeria of 1984 and Casamance of Senegal; Nigeria of 1984 and Casamance of Senegal;
Madagascar and Kenya; Madagascar and Nigeria of 1984; Kenya and Tanzania; respectively, in the same order.
In case of O.breviligulata, average values and those standard deviations in the
whole strains were found to be 9.16mm±0.62, 3.05mm±0.28, 1.89mm±0.17, 3.03±0.38, 4.90±0.60 and 1.62±0.12, respectively, in the same order. The largest and the
smallest values in the respective characters were ascertained in Nigeria of 1985 (K) and
north of Senegal (N); north of Senegal and Casamance of Senegal; Nigeria of 1984 and
Casamance of Senegal; Casamance of Senegal and north of Senegal; Casamance of
Senegal and Nigeria of 1984; Casamance of Senegal and Nigeria of 1984, respectively, in
the same order.

In case of O.punctata, average values and those standard deviations in the whole
strains were found to be 6.30mm±0.53, 2.43mm±0.08, 1.53mm±0.05, 2.60±0.22,
4.14±0.30 and 1.60±0.06, respectively, in the same order. The largest and the smallest
values in the respective characters were ascertained in Tanzania (P) and Kenya of 1985
(R); Tanzania and Kenya of 1985; Tanzania and Kenya of 1984; Kenya and Tanzania;
Kenya of 1984 and Kenya of 1985; Kenya of 1984 and Kenya of 1985, respectively, in
the same order.
In case of O.brachyantha, average values were found to be 9.01mm, 1.82mm,
1.40mm, 4.96, 6.50 and 1.31, respectively, in the same order.
Basing on the analyses of the data obtained in the field survey, morphological,
genetical and ecological characters, geographical, ecotypic and varietal differentiations could be discussed and concluded in the future.
