Table 5 2016 incidence of ToLCD and availability of ToLCD-resistant varieties in participating countries
From: Connecting smallholder tomato producers to improved seed in West Africa
Country | Current incidence of ToLCD and in-country seed supply | Commercially available ToLCD-resistant varieties | Comments on tomato varieties that are currently cultivated |
|---|---|---|---|
Benin | ToLCD causes significant losses during the dry and fresh tomato season in the north and south of the country | ‘Nadira’ ‘TLCV15’ | ‘LetyF1’ (De Ruiter Seed, now Monsanto) was distributed in pre-extension field trials but was rejected due to fruit size ‘Nadira’ (Tropicasem) is grown in the South but is not well adapted to that region, some of the big tomato producers unsuccessfully experimented with it (trials were done in the North). This variety has not become very popular with growers due to the seed price ‘TLCV15’ (AVRDC) is popular with growers who have worked with INRAB. This is the only variety which INRAB multiplied for sale, and the only variety which INRAB registered for the national vegetable seed catalog |
Niger | ToLCD is currently a problem in the region Niger Semence (formerly Tropicasem/Technisem/Sahéliasem, Agrimex) are the distributors in the country. Due to a lack of improved tomato varieties, farmers grow local varieties of pepper and onion | ‘Nadira’ ‘Mongal’ | ‘Nadira’ and ‘Mongal’ (Tropicasem) are recommended for cultivation in the rainy season and are on sale in Ag retailers ‘RomaVF’ (Tropicasem) is currently on sale and is popular; this was the susceptible check in the field trials and in the agroinoculation test |
Mali | ToLCD is still a problem in the region | ‘Nadira’ ‘OPB 149’ ‘OPB155’ | ‘Roma VF,’ ‘UC-82,’ ‘Rossol VF’ are the most popular varieties, but they are susceptible to ToLCD. ‘Nadira’ is not the most popular variety, but farmers who know its tolerance to ToLCD prefer it to the susceptible varieties Recently, open-pollinated cultivars ‘OPB 149’ and ‘OPB155’ have been released to farmers in Kati, Baguineda and Niono. These varieties were developed and distributed to farmers by Institute d’Economie Rurale (IER) in collaboration with the IPM Innovation Lab. These varieties have been found to produce good yield under ToLCD pressure and have been well received by farmers Popular with the local farmers, but currently unavailable in country are: ‘Atak’ (Enza Zaden Benelux B.V., now Enza Zaden), ‘Bybal’ (Enza Zaden Benelux B.V., now Enza Zaden), ‘Cheyenne E448’ (Syngenta AG, now Syngenta), ‘HA 3060’ (Hazera Genetics, now Hazera), ‘H8804’ (Heinzseed) and ‘Shasta’ (Harris Moran Seed Company Inc, now Harris Moran) |
Ghana | In Ghana, ToLCD causes significant losses during the dry and fresh market season Both local (Manoma) and international seed distributors (Agrimex and Technisem) distribute seed | ‘Nadira’ ‘GemPride’ | The most popular varieties are: ‘Pectofake,’ ‘Petromech,’ ‘Ada Lorry Tyre,’ ‘Power Rano,’ ‘Burkina’ and ‘Ada Lorry Tyre,’ local landraces susceptible to ToLCD |
Senegal | There is a lack of open-pollinated (OP) varieties adapted to wet conditions and resistant to diseases such as ToLCD | ‘GemPride’ ‘Nadira’ | ‘GemPride’ (Seminis, now Monsanto), ‘Nadira’ and ‘Yaqui’ (Tropicasem) are very popular ‘HMX 4810’ (Harris Moran Seed Company, now Harris Moran) was very popular with farmers, but seed supply was a bottle neck |
Burkina Faso | There is currently a shortage of tomato; ToLCD is still a major problem | ‘Nadira’ ‘GemPride’ | ‘Nadira’ (Tropicasem) and ‘GemPride’ (Seminis, now Monsanto) have been selected by contract farmers for a tomato-processing facility called STFL (La Société de transformation des fruits et légumes) located in Loumbila |
Togo | In areas where improved tomato varieties are not available or too expensive, farmers grow other vegetables such as onion, eggplant and okra | ‘TLCV15’ (AVRDC) was popular with farmers. Current information regarding cultivation is unknown |
