  • The only standard water-saving and drought-resistant rice variety for the southern rice region has been bred in Shanghai

    The Shanghai Academy of Agricultural Sciences announced on the 16th that Shanghai agricultural scientists have bred the only upland rice control variety for regional trials in the southern rice region and the first japonica-type upland rice variety in the southern rice region to pass national approval, and have built China's most complete rice drought-resistance identification and evaluation system and germplasm resource platform. Shanghai has become the country's main base for rice water-saving and drought-resistance research. According to Gu Xiaojun, vice president of the Shanghai Academy of Agricultural Sciences, the "Zhonghan No. 3" bred by scientists here is the first upland rice variety in China's southern rice region to pass national approval, and has been

  • New upland rice variety developed in Shandong, agronomist Xu Defang successfully breeds it

    In the golden autumn season, a new upland rice variety carefully cultivated over 3 years by Xu Defang, an agronomist at the Dongying Branch of the Shandong Academy of Agricultural Sciences, has achieved a bumper harvest. According to calculations, it yields more than double that of the current upland rice variety 297, with a yield of 600-650 kg per mu, marking a breakthrough in China's upland rice breeding. Xu Defang used more than 30 ancestral lines provided by Professor Li Zichao of China Agricultural University, discovered a dwarf-stalk mutant line from the tall-stalk line 33-1, and from it selected a group of 9 lines, namely early-maturing, glutinous, early

  • Introduction to the Renowned Upland Rice Variety Zhonghan 3

    Variety Approval Number: Guoshendao 2003030 Crop Type: Rice Variety Name: Zhonghan 3 First Breeding Institution: China National Rice Research Institute Variety Source: Systematic selection from CNA6187-3 Characteristics: This variety is a long-grain japonica conventional upland rice variety, with a growth period of 120-125 days, maturing 2-7 days later than the Brazilian upland rice IAPAR 9. Plant height is 130 cm, plant type is relatively compact, growth is luxuriant, and flag leaves are erect. Stems, leaves and husks are all smooth (glabrous), early growth is vigorous, leaf color is dark green, and later

  • Kenya Launches New Upland Rice Variety

    More than 300 farmers in Kenya are benefiting from a newly developed rice variety that has a shorter growing period, matures faster, and can also withstand harsh weather and disease. This rice variety, designated NaricIII, is an upland rice variety. However, unlike other upland rice varieties such as SupericaI, II and Abironi, which mature after 120 days and 5 months respectively, this new variety can mature in just 3 months. In addition to its high maturation rate, what pleases farmers most

  • Detailed Explanation of Key Cultivation Techniques for Upland Rice in Heilongjiang

    This year, farmer Sun Baoxiang of Heli Village, Renmin Town, Anda City, Heilongjiang Province, introduced the new upland rice variety Hanadao 65 from the Chinese Academy of Agricultural Sciences in Beijing, and achieved success in a trial planting of 10 mu. Due to severe drought this year, but with the careful cultivation by technicians and farmers, the actual harvest of upland rice grain in autumn was 2521 kg, with an average yield of 252.1 kg per mu. Although the yield of upland rice was not high during the three years of major disasters, the success of this upland rice planting has blazed a new path to wealth for the future development of upland rice production. 1. Quality varieties increase benefits, growth days

  • How is upland rice cultivated? These technical points need to be mastered

    Upland rice cultivation should master the following points: (1) Select a suitable sowing period according to variety characteristics. Generally the same as the local early and middle rice. (2) Choose plots with deep soil plough layers and good water retention. Mountainous land with steep slopes, shallow plough layers and high coarse sand content is not suitable for planting upland rice. (3) Deep ploughing and fine preparation, with sufficient base fertilizer. Plough layer over 15cm, bed width about 1 m. Apply base fertilizer per mu by banding or hole application: phosphate fertilizer 50 kg, potassium fertilizer 10 kg, farmyard manure 500 kg. (4) Direct seeding or seedling raising and transplanting. Direct seeding can be drilled

  • Detailed Explanation of Upland Rice Cultivation Techniques: From Sowing to Field Management Key Points

    Upland rice refers to the practice, under dryland conditions, of selecting high-quality rice varieties with relatively strong drought tolerance, adopting dry direct seeding, relying mainly on natural rainfall throughout the growth period, and appropriately supplementing water during drought in key growth stages, so that rice can grow and develop normally and flower and set seed under relatively moist soil conditions. The key points of upland rice cultivation techniques are introduced as follows: 1. Variety selection. Because the sowing period of upland rice is later than the seedling-raising period of paddy rice, varieties with early maturity should be considered in variety selection. Recently approved at the national level in our province

  • Successful breeding of the new upland rice variety Xiahan 51

    This achievement is an early-maturing japonica-type upland rice with strong drought resistance, high yield, and average grain quality. It is susceptible to rice blast and resistant to narrow brown leaf spot, and is suitable for upland cultivation. Plant height is 86.8 cm, the plant type is relatively compact, the leaves are erect at the seedling stage, the leaf color is dark green, and growth is steady; growth is vigorous in the mid-to-late stages, with relatively high tillering ability and productive tiller rate, and relatively strong lodging resistance. Panicle length is 15.1 cm, total grains per panicle are 88-90, seed-setting rate is 90%, and 1000-grain weight is about 25 g. Disease resistance: leaf blast grade 3, neck blast grade 7, narrow brown leaf spot grade 1. Main grain quality indicators

  • Analysis of the Current Status and Existing Problems of Upland Rice Production

    Upland rice, also known as dryland rice, is a type of cultivated rice with strong drought resistance, tolerance to poor soil, and suitability for dryland direct seeding and dryland management. It can be planted in any soil suitable for growing major dryland grain crops such as wheat and corn. It does not require water layer management throughout the entire growth period, and its irrigation volume is only 1/4 to 1/10 that of paddy rice. Upland rice is more drought-tolerant and barren-tolerant than paddy rice, and has the water-saving characteristics of low input and high output. I. Overview of World Upland Rice Production Currently, the world's upland rice planting area is 0.18 billion hectares. In West Africa, upland rice accounts for more than 75% of the rice growing area, and in

  • Israeli upland rice is a premium variety among upland rices.
