Sugarcane varieties for hilly areas

The North Central Institute of Agricultural Science and Technology (Vietnam Academy of Agricultural Sciences) has researched and successfully created the VD00-236 sugarcane variety with high yield and quality suitable for the ecology of hilly areas.

Origin: VĐ00-236 (Viet Duong 00236) was successfully crossbred in 2000 by the Guangzhou Sugarcane Industry Research Institute (China) between the Viet Duong 73-204 variety and the CP72-1210 variety. VĐ00-236 was introduced to Vietnam in 2007 and has been successfully tested and put into production in many localities. VĐ00-236 was arranged by the North Central Agricultural Science and Technology Institute for basic testing from 2011-2013 in Tay Hieu commune, Nghia Dan district, Nghe An (sugarcane crop and sugarcane crop 1); Production testing from 2013-2014 (sugarcane young crop and sugarcane original crop 1) in Tay Hieu commune (Nghia Dan) and Cong Chinh commune, Nong Cong district, Thanh Hoa with sugarcane varieties Roc10, QD93-159, VL6, QD94-119 were selected as research materials; in which Roc10 is the control variety. Monitoring results through testing years show: - Morphological characteristics: Large, even stem. Stem internodes are slightly conical in shape, without germ grooves. Stem internodes are light yellow, turning yellow-green when exposed to sunlight. Bud eyes are small, round-ovate. Germination wings are of medium width. Leaf sheaths are hairless. Leaf ears are lanceolate, outer leaf ears are triangular. - Industrial characteristics: Germination is fast, concentrated, high germination rate (51.3%), higher than the control Roc10 (50.8%).

High yield sugarcane variety VD00-236.

The initial tillering period is a bit slow, then faster. The growth rate is stable and even. The green leaves last long, without losing leaves during the harvest period. The density of the plant at the end of tillering is high (fluctuating around 129.9 thousand plants/ha), good resistance to lodging. The stem roots are numerous but do not affect the quality. In terms of yield and sugar content, among the experimental varieties, VĐ00-236 is always at the top. In Nghe An, VĐ00-236 achieved a yield of 89.4 tons/ha in the young sugarcane crop and 98.3 tons/ha in the first original sugarcane crop, an increase of 27.53% in the young sugarcane crop and 28.27% in the first original sugarcane crop compared to the control. In Thanh Hoa, the yield of VĐ00-236 reached 92 tons/ha in the young sugarcane crop, an increase of 38% compared to the control, and in the first original sugarcane crop it reached 101.1 tons/ha, 39% higher than the control. VD00-236 has the highest sugar content among current varieties in production and reaches an average of 12.3%, 15 - 20% higher than the control variety Roc 10.

- Adaptability: VĐ00-236 is a sugarcane variety with high quality and yield, wide adaptability, especially to ecological conditions in hilly areas, has a short growing period (harvestable after 11 months of planting), can be planted in separate seasons, contributing to increasing efficiency in raw material production and sugar processing. VĐ00-236 is resistant to smut, virus mosaic disease and brown stripe disease. According to the recommendation of the North Central Institute of Agricultural Science and Technology, VĐ00-236 has a short growing period and wide adaptability.

Therefore, in the coming time, Nghe An needs to have policies to encourage farmers to expand their planting area, especially in hilly areas in some key sugarcane districts, to contribute to increasing income, increasing economic efficiency for sugarcane growers and stabilizing raw materials for sugar factories. - Note when cultivating: This is a hybrid sugarcane variety created for the subtropical region of Southern China, for soils with average fertility, arid and sloping, or for highland farms without irrigation water. This sugarcane variety is tolerant to intensive cultivation and responds very well to phosphate and potassium fertilizers....
