内容記述

During the periods from October to November in 1984, from August to November
in 1985 and from May to August in 1988, the writer had been sent to 8 countries of Africa, i.e., Madagascar, Tanzania, Kenya, Nigeria, Ivory Coast, Liberia, Senegal and Gambia, for collection of the wild and cultivated rices. During the trips, 284 strains of wild rice, i.e., 190 of Oryza longistaminata, 49 of O.breviligulata, 44 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
the standard deviations in the whole strains were found to be 8.47mm±0.63. 2.36mm±0.20, 1.60mm±0.11, 3.61±0.26, 5.31±0.33 and 1.48±0.09 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. In general, strains collected in Senegal, Nigeria
and Madagascar were ascertained to be long, large and small types, respectively.
In case of the O.breviligulata, average values and the standard deviations in the
whole strains were found to be 9.22mm±0.80, 3.04mm±0.25, 1.86mm±0.16, 3.06±0.41, 5.00±0.66 and 1.64±0.09, respectively, in the same order. The strains collected in
Ivory Coast and Nigeria were ascertained to be long, wide and thick types, respectively.
Ratios of length to width, of length to thickness and of width to thickness were found to be the largest in the strains collected in Ivory Coast.
In case of the O.punctata, average values and the standard deviations in the whole
strains were found to be 6.10mm±0.42, 2.35mm±0.12, 1.52mm±0.05, 2.61±0.18,
4.04±0.26 and 1.56±0.08, respectively, in the same order. The longer, the wider and
the thicker characters were found in the strains collected in Kenya.
In case of the 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.
Several character-specificities in habitat, morphological points and connection with
one another were found. Basing on the analyses of the data obtained in the field survey, however, morphological, genetical and ecological characters, geographical, ecotypic and varietal differentiations could be discussed and concluded in the future.
