Multi-resistant high-quality sesame-Zhongzhi 10

Based on the principle of gene complementarity and accumulation, Zhongzhi 10 was selected by compound hybridization of 5 varieties and selected by artificial waterlogging, natural disease nursery and main economic characters. The variety was examined and approved by Hubei Province and National crop Variety approval Committee in 1994 and 1997 respectively.

Characteristics: this variety is branched, each leaf axil three flowers, capsule four-angled. The plant height is about 150 cm, the height can reach 2 meters, the effective branches are about 4, the number of capsules per plant is 100-200, the number of grains per capsule is about 65, and the weight of 1000 seeds is about 2.6 grams. The plant is stout, the growth is neat, the seedling stage is robust, the flowering is late, the florescence is concentrated, and the maturity is consistent. When mature, the stem and fruit are yellow and are not easy to crack the capsule. The seed coat is white, the seed oil content is about 56%, and the protein content is 23.58%. It is a high-quality foreign trade commodity. It has strong drought and waterlogging tolerance and high seedling preservation rate. No matter in natural disease nursery or inoculation identification, compared with Zhongzhi 8, Xiangzhi 2 and Yuzhi 2, Zhong Zhi 10 was resistant to stem point blight and Fusarium wilt in all levels of regional tests. The normal growth period of summer sowing is about 95 days, and that of autumn sowing around July 10 is about 85 days. The yield per mu in the national area test was 61.51 kg, an increase of 6.07% over the unified control variety Yuzhi 2, and the production test was 66.87 kg per mu, an increase of 15.19%. Zhongzhi 10 is suitable for planting in Hubei, Henan, Anhui, Jiangxi, Guangxi, Guizhou and other provinces and cities.

Cultivation points: in cultivation, summer sowing should be sowed from mid-late May to early June, with a density of 0.6-7000 plants / mu, the whole growth period is about 95 days, autumn sowing is no later than July 10, and the whole growth period is less than 80 days. Fertilization is mainly based on base fertilizer, pay attention to the proportion of NPK. On the basis of deep trench and narrow box, pay attention to clear ditch and drainage, and time seedling to control diseases and insect pests.
