The root bark, meat and core are all orange-red and cylindrical, the root length is about 18 cm, the root diameter is 4.8 cm, and the root weight is 200 to 250 grams. The total soluble sugar is 4.92%, and β-carotene is 40.4 mg / kg. The root shape of this variety is very neat, the epidermis is very smooth, and it has the characteristics of tomb resistance, early maturity, high yield, high yield and so on.

(2) the most suitable sowing time is when the ground temperature at the depth of 5 cm is stable at 8 ℃ ~ 15 ℃. Suitable for planting in the north, Beijing and Tianjin are suitable for mid-and late-March, the south of North China is suitable for late February to early March, and northwest and northeast alpine areas can sow seeds from early April to early and mid-May.

2. Mendelian characteristics

Mendel carrot is a new variety selected and bred in Japan, which is suitable for planting in protected areas in early spring and open fields in summer and autumn.

It is resistant to low temperature and tomb, so it is an ideal new variety of carrot sown in spring.

(2) it can be cultivated all over the country. The thermal insulation greenhouses and greenhouses in Tianjin and its surrounding areas are sown in early February, those in plastic greenhouses (plus plastic film) are sown at the end of February, and the planting covered with plastic film is sown in late March. The sowing rate is 300 grams per 667 square meters. The row spacing is 60.8 cm × 30 cm, and 30000 seedlings are retained per 667m2. The plastic greenhouse or greenhouse is released at noon when the temperature is high, and closing the tuyere when the ambient temperature of the plant reaches 18 ℃ can reduce the risk of tomb extraction, harvest and sell in time.
