 note = {During the trip from October to November in 1985 in Senegal, 67 strains of wild
rice, i.e., 42 of Oryza longistaminata CHEV. et ROEHR., 24 of Oryza breviligulata CHEV.
et ROEHR., and 1 of Oryza brachyantha CHEV. et ROEHR., were collected and many
populations of the former 2 species were observed. Their localities and habitats were reported in detail. Locality names are as follows; Ziguinchor, Simbandi, Tanaff, Kolda,
Saresara, Tiapa, Anambe, Sefa, Bounkiling, Tangouri, Bignona, Kafoutine, Dioloulou,
Goudomp, Biaobe, St. Louis, Richard Toll, lac du Guiners, Matam, Nianga, N'Dioum;
Bassè, Faraba Banta, Kafuta, Brikama (GAMBIA).
Strains of O.longistaminata and O.breviligulata were divided into two groups, i.e., Group A — strains collected in southern part of Senegal (Casamance), Group B
— strains collected in northern part of Senegal (Matam).
In case of O.longistaminata, lengths, widths, thicknesses, ratios of length to width, ratios of length to thickness, ratios of width to thickness, were found to 8.68mm, 9.16mm, 8.76mm; 2.40mm, 2.57mm, 2.43mm; 1.60mm, 1.69mm, 1.62mm; 3.64, 3.58,
3.63; 5.45, 5.42, 5.44; 1.51, 1.52, 1.51 in Group A, Group B and through the both
groups, in the average values, respectively. It may be noticeable that the population of
No.149, collected in upland field near Matam, showed large values in length, width, L/T and W/T.
In case of O.breviligulata, these values were found to be 8.99mm, 8.87mm, 8.96mm; 2.91mm, 3.16mm, 2.98mm; 1.78mm, 1.95mm, 1.83mm; 3.12, 2.82, 3.04; 5.12,
4.57, 4.96; 1.65, 1.58, 1.64 in the same order in Group A, Group B and through the both groups, respectively. It may be noticeable that the populations of Nos. 122 and 150, collected in paddy field near Biaobe and in upland field near Matam, respectively, showed large values in length and L/W.
Average values of O.brachyantha were found to be 9.01mm, 1.82mm, 1.40mm, 4.96, 6.50 and 1.31 in length, width, thickness, ratios of length to width, of length to thickness, and of width to thickness, in average values, respectively.
In the analyses of the data obtained in the field survey, morphological and genetical
characters, ecotypic and varietal differentiations may be discussed in the future.},
