Vegetable & Horticultural Seed
High-value vegetable and horticultural varieties selected for East African climate, disease pressure and export market standards.
A vegetable farmer using untested open-pollinated varieties loses 30-40% of potential income to yield gap and market rejection.
High-value vegetable production for domestic urban markets and export buyers requires varieties that combine yield potential with the specific fruit quality, uniformity, shelf life and disease resistance attributes that buyers specify. Jos•Hansen supplies certified hybrid vegetable seed from Bejo and East West Seed covering tomato, pepper, onion, cabbage, french bean, cucumber and courgette, with variety selection guided by the specific market destination, growing environment and disease pressure of each production system. Every variety recommended for export market production is validated against the phytosanitary, grade and residue requirements of the target destination market.
Export-grade varieties
Tomato and french bean varieties recommended for export production are selected against buyer grade specifications for fruit size, uniformity, colour and firmness, the criteria that determine pack-out percentage and price grade at the export packing station. Export variety selection is updated annually as buyer specifications change and new varieties are trialled against destination market requirements.
TYLCV resistance
Tomato yellow leaf curl virus resistance is a prerequisite for commercial tomato production in lowland East African growing areas where whitefly vector populations make susceptible variety production uneconomical. Jos•Hansen tomato varieties carry confirmed TY resistance sourced from Ty-1, Ty-2 or Ty-3 resistance gene combinations.
Processing varieties
Tomato processing varieties with high soluble solids, thick pericarp and concentrated set are available for supplying tomato paste and puree processors in East Africa, providing a formal offtake channel for smallholder and commercial tomato producers with access to irrigation.
Hybrid tomato varieties combine TYLCV resistance and export grade quality.
Tomato yellow leaf curl virus causes complete crop failure in susceptible varieties when whitefly populations exceed the virus transmission threshold, which occurs in most lowland East African growing environments during the dry season. Jos•Hansen hybrid tomato varieties carry stacked TY resistance gene combinations that maintain commercial yield in high-whitefly environments without relying on insecticide programmes intensive enough to create residue problems on export consignments. Fruit quality attributes including size uniformity, red colour development, firmness and shelf life are evaluated against export packing station grade specifications before any variety is listed for export market production. Varieties for domestic market production are evaluated against local consumer preference for fruit size, colour depth and flavour profile in the specific target market, separate from export variety listings.
French bean varieties meet EU export grade standards from seed selection.
Kenya french bean exports to the EU and UK operate under phytosanitary protocols that specify varietal pest resistance, maximum residue limits and pod uniformity standards. Jos•Hansen french bean variety listings are sourced from Bejo Zaden, the primary supplier to Kenyan export producers, with varieties selected for pod length uniformity, straight pod set, Halo blight resistance and post-harvest shelf life at 4°C. Variety selection guidance includes recommended plant population, picking interval and pack-out percentage expectations for each variety under typical Kenyan highland growing conditions. Agronomist support at farm trial stage is included for producers scaling up from smallholder to commercial export volumes.
Onion varieties match the specific market and storage requirements of each season.
Onion variety selection in East Africa requires matching days-to-maturity to the available growing season, pungency and colour to the target market preference, and skin tightness to the post-harvest storage duration required between harvest and market sale. Short-day hybrid varieties recommended for low-latitude East African growing are selected for firm external skin, tight neck closure and 3-6 month storage stability at ambient temperature. Jos•Hansen onion variety listings cover red, brown and white skin types for different market and processing requirements, with days-to-maturity options from 90 days for quick-rotation systems to 120+ days for commercial production targeting the long dry season storage premium. Trial packs are available for producer testing before bulk seed commitment.

Why Vegetable.
Export grade from seed
Hybrid varieties selected against buyer grade specifications deliver higher pack-out percentage and fewer grade rejections at the export station than open-pollinated alternatives.
TYLCV resistance built in
Stacked TY resistance gene combinations maintain commercial tomato yield in high-whitefly environments without the insecticide intensity that creates export MRL problems.
Market-specific selection
Separate variety lists for export, domestic, processing and institutional markets ensure each variety recommendation fits the actual buyer quality and grade requirements.
Trial pack availability
Trial seed packs allow producers to evaluate variety performance in their specific growing environment before committing to commercial season seed volume.
