Zhongyan 958 Tomato Cultivation Technology Zhongyan 958 is a new generation of indeterminate hybrid tomato variety developed by the Vegetable Research Group of the Chinese Academy of Sciences. Both parent lines were introduced from Israel and have undergone extensive comparative trials in greenhouse conditions. This variety is considered a promising successor to popular varieties like "Gold Shed" and "Bull," offering significant improvements in growth potential, fruit size, and resistance to environmental stress. It overcomes common issues such as weak growth, small fruits, deformed fruits during winter cultivation, and early aging. This variety represents a major breakthrough in four generations of hybrid development and has the potential to redefine the future of tomato production. Key Characteristics
1. **Strong Growth Potential**: This indeterminate type can bear 8–10 trusses. The stems are thick, roots are well-developed, leaves are large, and the plant has good photosynthetic efficiency.
2. **Superior Fruit Traits**: The fruit has better firmness, color, smoothness, and overall quality compared to current domestic hybrids.
3. **Temperature Tolerance**: It performs well under both low and high temperatures, with high fruit set rates and minimal deformities or cracking. Fruits grow well even in challenging conditions.
4. **Good Commercial Value**: The fruit is uniform in size, bright pink when ripe, and has no green shoulders. The skin is thick and durable, making it ideal for long-distance transportation and storage.
5. **Strong Disease Resistance**: Resistant to leaf mold, tobacco mosaic virus (TMV), early and late blight, root-knot nematodes, and gray mold. It shows high resistance to most physiological races of leaf mold. Cultivation Tips
Compared to other varieties, Zhongyan 958 requires careful attention to several key aspects:
1. **Dwarf Seedlings**: If any dwarf seedlings appear, they should be removed at planting. If already grown, they can be pruned and trained for multiple side branches. Note that these dwarf plants still produce large fruits, around 250 grams each.
2. **Seedling Management**:
- Prepare nutrient-rich soil with decomposed organic manure, along with appropriate compound fertilizer and fungicides.
- In northern regions, seeds should be soaked and germinated before sowing, once 30% of the seeds show white sprouts.
- Due to its vigorous growth, avoid excessive moisture and temperature. Maintain daytime temperatures between 20–25°C and nighttime temperatures between 12–15°C. Avoid temperatures below 12°C at night.
- Strong seedlings should have thick stems, large leaves, and 7–8 leaves with buds.
3. **Planting Density**: Plant at a reasonable density based on season and growth. For winter and spring protection, plant 2,800 plants per acre with 6–8 trusses. For open fields, plant 3,000 plants per mu with 4–5 trusses.
4. **Fertilization and Watering**:
- Apply base fertilizer with organic compost (5,000 kg per mu) and supplemented with compound fertilizer, urea, superphosphate, and potassium.
- Control water before fruit set and start fertilizing when the first truss reaches 50g. Use compound fertilizer with added calcium and trace elements like boron and magnesium.
5. **Temperature Control**:
- Seedling stage: Daytime 20–25°C, nighttime 12–15°C.
- Flowering and fruit set: Daytime 25–28°C, nighttime 15–17°C.
- Fruit development: Daytime 24–28°C, nighttime 16–18°C. Ensure floor temperature stays above 17°C.
- Ventilate when temperatures exceed 32°C and maintain proper light conditions, especially on cloudy days.
6. **Fruit Thinning**: Use the 2,4-D method for optimal flowering. Apply a lower concentration to avoid “spike†formation. Thin fruits after the first ear, leaving 3–4 per cluster.
7. **Harvest Timing**: Harvest promptly when fruits begin to change from blue-white to red to prevent cracking due to moisture fluctuations. Zhongyan 958 is an excellent choice for modern tomato growers looking for high yield, disease resistance, and superior fruit quality. With proper management, this variety can significantly improve productivity and profitability in both greenhouse and open field settings.
