Characteristics and Traits of the Tomato Variety AVRDC No. 3

Variety source: Introduced from the Asian Vegetable Research and Development Center.

Main traits: early maturing, self-topping type, strong growth vigor, many fruits, cherry-type fruit, smooth and round, bright red color, single fruit weight about 13.5 g, soluble solids content up to 5.5%, good quality, good taste, high early yield, good productivity, 667 sq m, yield can reach more than 4000 kg, strong disease resistance, suitable for storage and transport, high economic benefit.

Cultivation points: suitable for early-maturing cultivation. For seedling raising in a cold bed in a greenhouse, sowing should be done in early November; for seedling raising in an electrically heated hotbed, sowing should be done in early January. Strengthen management during the seedling stage, cultivate strong seedlings, and at the 2-leaf 1-heart stage use nutrient pots for transplanting seedlings, with a seedling spacing of 10*10 cm. When there are 8-9 true leaves, transplant in time. For greenhouse cultivation, hardening is not needed; for open-field plastic film mulching cultivation, low-temperature hardening should be carried out one week before transplanting. Apply sufficient base fertilizer, with 3000 kg of decomposed barnyard manure and 40 kg of compound fertilizer per mu. Generally, the bed width is 1.4 m (including the ditch), with 2 rows per bed, and a plant spacing of 0.4 m. Use double-stem pruning. In the early fruiting stage, spray flowers with 10-15 ppm 4-CPA every 2-3 days to promote flower retention and fruit set. Strengthen fertilizer and water management; after fruiting, do not apply additional nitrogen fertilizer. A 0.2-0.5% potassium dihydrogen phosphate solution can be used for foliar topdressing to improve quality. Pay attention to controlling diseases such as gray mold, and harvest promptly when the fruits are red and ripe.
