Ten thousand taro 10 (sweet potato)

The main results are as follows: (1) Variety source: it was bred by Wanxian Institute of Agricultural Sciences in 1990 using Zhongzhai Yellow as female parent and 6511-88 as male parent.

(2) characteristics: the rate of large and medium potatoes of this strain is 60%, potato pieces contain 14.87% starch, 2.32% crude protein, and vitamin C 18.4 mg / 100 g fresh potatoes. Tested by the plant protection department in the field, it was highly resistant to virus disease and bacterial wilt, but more resistant to late blight. The seedling is neat, the potato is round, the yellow skin is yellow, the tuber is early and concentrated, and the planting yield is higher in autumn.

(3) yield performance: in the 3-year provincial multi-site test from 1992 to 1994 (regarded as provincial regional trial), the average yield of fresh potato per mu was 1338.7 kg per mu, which was 2.7% lower than that of the public control virus-free Sichuan taro 56, and 6.3% higher than that of the landlord. In the production test in 1995, the yield of fresh potato per mu was 1267.0 kg, which was 9.4% higher than that of the control Sichuan taro 56 and 29.8% higher than that of the local main planting. In the five pilot production experiments in the autumn of 1996, the average yield of fresh potato per mu was 799.9 kg, which was 11.0% higher than that of Sichuan taro 56.

(4) suitable planting area: suitable for planting in two seasons between Zhongshan and hilly areas below 1000 meters above sea level, and planting in one season above 1000 meters.
