内容記述 |
Sorghom bicolor is one the most important foods and forage crops in the world and its origin is supposed to be northeast Africa where a wide range of diversity has been reported for Sorghum spp. A collaborative genetic resources exploration between Japanese and Kenyan researchers was undertaken in Kenya to collect Sorghum spp. and other forage species from January 27 to February 20, 1997. The exploration trip route (Fig. l) coverd the high altitude Central regions around Nairobi and Mt. Kenya, the Southwest regions around Lake Victoria up Kitale, the low altitude Northwest regions up to Lake Turkana, where it was very hot and dry and the Coastal regions up to Mombasa, where it was relatively hot and dry. The Northeast desert regions and the areas near the borders of Somalia, Ethiopia and Sudan were excluded due to security concerns. The exploration itinerary is shown in Table 1. It was the dry season after the minor rainy season and the second harvest time for S. bicolor after regrowth from the first harvest. The best time to collect sorghums is around July after main rainy season. The time we visited Kenya was the second choice to collect Sorghum seeds, so that we stopped at many markets to get local strains harvested in the farmers' field. We got many seeds of S. bicolor and several Eleusine coracana samples and some Zea mays from the markets at almost every town in Kenya. Though exploration and collection was focused on local varieties of S. bicolor and wild type of Sorghum spp., some Eleusine coracana (African millet), Panicum maximum (guinea grass) and Chloris gayana (Rhodes grass), etc. were also collected. Number of accessions collected is shown (Table 1). The total number of collected seeds was 219, and 217 accessions were introduced into Japan. The collected accessions consisted of 125 of S. bicolor, 17 of other Sorghum spp., 7 of Zea mays, 18 of Eleusine coracana, 17 of Panicum maximum, 15 of Chloris gayana, 10 of other tropical grasses, 9 of Leguminosae and 1 of Sesamum indicum (Table 2). One thirds of S. bicolor seeds were collected from markets. The seeds collected show a wide range of variability in seed color and head shape, plant height, etc. Among accessions of S. bicolor there are two accessions, white and good in quality, for which grains were completely covered by glumes. These strains might be a useful breeding material for bird resistance. The cultivation area of S. bicolor has been decreasing recently, while corn is increasing, because corn has a higher market price. Some giant types of Panicum maximum and tetraploid and wide leaved accessions of Chloris gayana were collected. These might also be useful breeding materials. We would like to thank the directors of Kenya Agricultural Research Institute and National Institute of Agrobiological Resources concerned with this successful collaborative exploration and collection of genetic resources carried out in Kenya. |
