Key Points of High-Yield Cultivation Techniques for Upland Rice Gaoshan No. 1
Upland rice Gaoshan No. 1 was bred from a wild upland rice that grows in the Dupangling area on the border of Hunan and Guangxi. Because this wild upland rice has long grown under harsh natural environmental conditions, it has strong resistance to pests, diseases and weeds, and is also tolerant of poor soil and drought, with a particularly well-developed root system. The Gaoshan No. 1 variety is suitable for both paddy and upland cultivation. In 2000, it was trial-planted in Tancheng County, Shandong Province and Wencheng County, Zhejiang Province, with the highest yield reaching 9750 kg/hectare and an average yield of 7687.5 kg/hectare, an increase over local hybrid rice

Breeding and High-Yield Cultivation Techniques of the Rice Variety Lindao 12
1 Breeding history: In 1999, the Linyi City Rice Research Institute used radiation mutation breeding, treating 500 g of Yujing 6 seeds with 60Co alpha-rays at a dose of 40,000 roentgens, and planted the Mo generation that year; the population showed high sterility, and all seeds (M1 generation) were harvested in autumn; in the winter of the same year, winter multiplication in the south was carried out to add a generation, planting the M1 generation, and the population showed high segregation, and all M2 generation seeds were harvested. In 2000, the quartering bulk breeding method was used, planting the M2 generation, and in autumn superior plants were selected from the mutant population.

Detailed Explanation of Key Techniques for Super-High-Yield Cultivation of Double-Season Rice in South China
(1) Sow at the right time and cultivate strong seedlings. For early rice, use dry-raised seedlings, with a seeding rate generally of 90 g/m2 and a sowing period in mid-to-late March; for late rice, use sparse sowing for strong seedlings or two-stage seedling raising, with a seed rate of about 1.0 kg per mu. (2) Ridge and bed cultivation. Bed width 3-4 m, ditch width 0.2-0.25 m, and open surrounding ditches well to facilitate water management and field operation management. (3) Wide-row close planting. The planting density is 30-40 hills/sq m, with a row spacing of about 25 cm. Generally, early rice has 3-4 seedlings per hill, and late rice is transplanted as single seedlings or double seedlings, ensuring
